### Solved Questions for Work Done by Gravity

1) Calculate the force of gravitation between the earth and the Sun where the mass of the  earth = 6 x 1024 kg and the mass of the Sun = 2 x 1030 kg. The average distance between the two is 1.5 x 1011 m.

Ans. The mass =6 x 1024 kg

The mass of the Sun = 2 x 1030 kg

The average distance between the earth and the Sun, (d) =  1.5 x 1011 m

The gravitational constant (G) = 6.67 x 10-11 Nm2 /Kg2

The gravitational force of attraction between m1 and m2 can be found out using this formula

F=Gm1m2r2

F=6.67×10−112×1030×6×1024(1.5×1011)2

F = 3.557 × 1022 N.

2) A body of 55 kg falls from the fifth floor of a building 90 m high. What is the work done by gravitational force?

Answer: The body falls within the action of the force of gravity. To calculate the work done, this formula should be used: m = 55 kg, g = 9.8 m/s2, h = 90 m.

W = 55 kg x 9.8 m/s2 x 90 m

W = 48,510 J.

Therefore, this is the work done by the gravitational force.
