Cross Product Formula
The area between any two vectors can be calculated using the Cross Product Formula. The area of the parallelogram that is spanned by the two vectors is determined by the magnitude of the resultant vector, which is determined by the Cross Product Formula.
The binary operation on two vectors in three dimensions is called a Cross Product Formula. Once more, it produces a vector that is perpendicular to both vectors. The righthand rule is used to calculate the cross product of two vectors.
The righthand rule states that any two vectors must provide a result that is perpendicular to the other two vectors. One may also determine the size of the resulting vector using the Cross Product Formula.
Different types of vectors are defined in vector algebra, and different operations, such as addition, subtraction, product, and so forth, can be carried out on these vectors. The Cross Product Formula of two vectors is described along with the general Cross Product Formula, properties, and examples on the Extramarks website and mobile application.
In three dimensions, the Cross Product Formula is a binary operation on two vectors. A vector that is perpendicular to both vectors is produced as a result. A B stands for the vector product of two vectors, a and b. The resulting vector is parallel to both a and b. Cross goods are another name for vector products. When two vectors are crossproducts, a vector is produced that can be calculated using the righthand rule.
Students should be sure to pay attention to the planes they dwell in and the equations provided in order to compute the cross product for a particular set of vector equations. Students might look at the examples given on the Extramarks website and mobile application to improve their understanding of the fundamentals of this Cross Product Formula.
The following are the applications of the Cross Product Formula:
A Cross Product Formula is mostly used in physics and astrology to deal with rotating bodies.
 Cross Product Formula can also be used to determine the vector that is perpendicular to other supplied vectors.
 Cross Product Formula conveys an idea of the direction, size, and occasionally speed of the object set in motion.
 They as well as other formulas are utilised in calculus. Determinants may be produced through cross products.
 Cross Product Formula describes an object’s direction and force.
 Sometimes a cross product of two vectors can be used to determine the gravitational field’s direction.
Students can use the right hand thumb rule to determine the direction of the cross product of two nonzero parallel vectors a and b. The thumb on the right hand indicates the direction of the cross product when students point their index finger along vector a and their middle finger along vector b.
Three vectors are used to form the triple cross. In other words, the cross product of two additional vectors and one vector.
Cross Product Definition
Vector product or cross product of two vectors
A→ and B → is denoted by A → × B → and its resultant vector is perpendicular to the vectors.
A→ and B →
Below are a few points to remember in the case of the Cross Product Formula:
 Every time two vectors are crossed, a vector quantity results.
 If the order of the vectors is altered in a vector product, the resulting vector has a negative sign.
 the path of:
A → × B → is always parallel to the plane that contains
A → and B →
 Any two linear vectors’ cross product is always a null vector.
Cross Product of Two Vectors Meaning
The process of multiplying two vectors is called the Cross Product Formula. The multiplication sign (x) between two vectors indicates a cross product. Cross Product Formula has a threedimensional definition and is a binary vector operation. The third vector that is parallel to the two original vectors is the cross product of the two original vectors. The area of the parallelogram that separates them provides information about its magnitude, and the righthand thumb rule can be used to identify its direction. Since the outcome of the cross product of vectors is a vector quantity, the Cross Product Formula of two vectors is also referred to as a vector product. Students will gain a deeper understanding of the Cross Product Formula of two vectors on the Extramarks website and mobile application.
A B stands for the vector product or cross product of two vectors A and B, and the resulting vector is perpendicular to the original two. While the dot product is used to identify the length of a vector or the angle between two vectors, the Cross Product Formula is typically used to determine the vector that is perpendicular to the plane surface spanned by two vectors. In three dimensions, the cross product of two vectors, such as A B, equals a vector at right angles to both.
Cross Product of Two Vectors
Cross product is a type of vector multiplication that is carried out between two vectors of various forms or natures. A vector has a direction and a magnitude. The Cross Product Formula and dot product can be used to multiply two or more vectors. The resultant vector is known as the Cross Product Formula of two vectors or the vector product when two vectors are multiplied together, and the product of the vectors is likewise a vector variable. The resulting vector is parallel to the plane in which the two provided vectors are located.
Two vectors of different types or natures are multiplied in a cross product, a sort of vector multiplication. A vector has a direction and a magnitude. Two or more vectors can be multiplied using the cross product or dot product. The resultant vector quantity from the multiplication of two vectors is also a vector quantity. The final vector product is the cross product of two vectors, often known as the “vector.” The two provided vectors are contained in a plane, and the resulting vector is perpendicular to that plane.
Cross Product Formula
If A and B are two separate vectors, then their cross product (AxB) will be perpendicular to both of them and normal to the plane in which they are both included. It is shown by the equation A x B= A B sin θ
Students will be able to comprehend this by using the example that if they have two vectors that are located in the XY plane, their cross product will result in a resultant vector that is located perpendicular to the XY plane, along the Zaxis.
The × symbol is used between the original vectors. The vector product, or the Cross Product Formula of two vectors is shown as:
→a×→b=→ca→×b→=c→
Where→aa→ and →bb→ are two vectors.
→cc→ is the resultant vector.
RightHand Rule – Cross Product of Two Vectors
Students can also determine the vector’s direction by applying the righthand rule to the Cross Product Formula of two vectors. The method that experts use to determine which direction the cross product of two vectors will go is as follows:
 Point the index finger in the first vector’s direction (A A).
 Place the middle finger in the second vector’s (B B) direction.
 The thumb is currently pointing in the direction of the Cross Product Formula of two vectors.
The righthand rule can be used to assist students in determining the direction of the unit vector.
Students can use this rule by stretching their right hand so that the middle finger is pointing in the direction of the second vector and the index finger is pointing in the direction of the first vector. The direction, or unit vector n, is then indicated by the thumb of the right hand. The righthand rule makes it simple for pupils to demonstrate that the cross product of vectors is not commutative. The illustration for the righthand rule is as displayed on the Extramarks website and mobile application if they contain two vectors A and B.
Cross Product of Two Vectors Properties
The Cross Product Formula features are useful for understanding vector multiplication clearly and for quickly resolving any issues that may arise when performing vector calculations. The following characteristics of the Cross Product Formula of two vectors are discussed and explained in great detail on the Extramarks website and mobile application.
Students can use properties to determine the cross product of two vectors. Finding the cross product of two vectors depends heavily on features like the anticommutative property and the zero vector property. Other properties besides these ones include the Jacobi property and the distributive property. On the website and mobile application of Extramarks, the crossproduct properties are listed.
The area of a rectangle with sides X and Y is represented by the Cross Product Formula of two vectors, which is equal to the product of their magnitudes. The Cross Product Formula becomes: = 90 degrees when two vectors are perpendicular to one another. As students are aware, sin 90° = 1.
The Cross Product Formula is a mathematical operation used to multiply two vectors. It is a binary vector operation in three dimensions. The Cross Product Formula of two vectors creates the third vector, which is parallel to the first two vectors. The area of the parallelogram that separates them determines its magnitude, and the righthand thumb rule determines its direction. Because the outcome of the cross product of two vectors is a vector quantity, the cross product of two vectors is often referred to as a “vector product.” As an illustration, try twisting a bolt using a spanner: The spanner’s length is one vector. Another vector is the direction in which we twist the spanner to tighten or loosen the bolt. The resulting twist’s orientation is parallel to both vectors.
Triple Cross Product
The triple cross product of the vectors is the cross product of a vector and the Cross Product Formula of the other two vectors. A vector is the triple cross product’s resultant. The triple cross vector’s resultant is located in the plane formed by the first three vectors. The vector triple product of these vectors will take a specific shape if a, b, and c are the vectors. Students can get a detailed explanation of the form on the Extramarks website and mobile application.
This makes use of u, v, and w values. Think about the equation u x (v x w). u x v x w u x v x w Keep in mind that (u x v) x w is parallel to (u x v). U and V determine this normal plane.
The vectors must be coplanar if the triple product of the vectors equals zero.
The triple product vector represents the parallelepiped’s volume. Any one of the three vectors is identified and displays zero magnitude if it is zero. Its perpendicular relationship to the plane can serve as an indicator for the vectors a and b. If the vector c also lies in the same plane as the resultant, then the dot product of the resultant with c will also be zero.
The vector triple product is a subfield of vector algebra. Students can learn about the cross product of three vectors by looking at a vector triple product.
If they practise the cross product of a vector along with the cross products of the other two vectors, they can compute the amount of the vector triple product.
As a result of this crossproduct, a vector quantity is produced. The result of the vector triple product’s simplification is the identity name BAC – CAB.
Practice Questions on Cross Product of Two Vectors
Cross Product Formula is important in many areas of science and engineering. The next two examples are both quite simple.
Example 1: Applying equal and opposing forces to the two diametrically opposed ends of the tap will turn it on. In this instance, torque is used. In vector form, torque is the cross product of the force vector and the radius vector, which measures the distance from the axis of rotation to the force application point.
Example 2: Using a spanner to turn a bolt: The spanner’s length is one vector. When tightening or loosening the bolt, we apply force to the spanner in this direction. The orientation of the twist that results is parallel to both vectors.
A vector that is orthogonal to the two provided vectors is produced when two vectors are crossproducts.
 The righthand thumb rule provides the direction of the cross product of two vectors, and the area of the parallelogram created by the initial two vectors, an a and b b, provides the magnitude.
 A zero vector results from the crossproduct of two parallel or linear vectors.
FAQs (Frequently Asked Questions)
1. The Cross Product Formula of two vectors is?
The third vector, which is perpendicular to the first two vectors, is produced by multiplying the cross product of the first two vectors. The area of the parallelogram formed between them provides the magnitude of the resulting vector, and the righthand thumb rule can be used to determine its direction. When the two vectors a and b are crossed, the result is a = b = c.
2. What does the Cross Product Formula achieve?
When students calculate the cross product of two vectors, we obtain a new vector that is perpendicular to the plane where the original two vectors were located. The product of the vectors’ magnitudes and the sin of the angle between them yields the magnitude of the resultant vector. a × b =a b sin θ.
3. What exactly are the two vectors' dot product and Cross Product Formula?
The dot product and Cross Product Formula are two alternative ways that vectors can be multiplied. Both of these vector multiplications provide distinct outcomes. As a result, the cross product produces a vector quantity, while the dot product produces a scalar quantity. The Cross Product Formula of two vectors is the vector product of two vectors, and the dot product is the scalar product of two vectors. The Cross Product Formula is sometimes referred to as a “vector product,” while the dot product is also referred to as a “scalar product.”
4. What Is the Cross Product of Two Vectors Right Hand Thumb Rule?
The direction of the resulting vector can be determined using the righthand rule for the crossproduct of two vectors. Their thumbs will end up pointing in the direction of the cross product of the two vectors if students point their right hand in the direction of the first arrow and curl their fingers in the direction of the second. The Cross Product Formula for determining the direction of the resulting vector is provided by the righthand thumb rule.
5. Why is Cross Product Sine?
Since the area of the parallelogram is determined by the cross product of two vectors, sine is utilized because it is the angle between the two original vectors.
