Question

What happens to the magnitude of the force of gravitation between two objects if: (a)
distance between the object is tripled? (b) mass of both objects is doubled ? (c) mass of
both objects as well as the distance between them is doubled ?

Answer 1

Answer:

A

If the distance between objects is trippled

The gravitational force is given by

F= m1m2

d^2

F = m1. m2

( 3d) ^2

F = m1. m2

9d^

B

If mass of both the objects is doubled

F= 2(m1.m2)

d^2

F= 2m1.2m2

d^2

C

If mass of both objects is doubled and distance is doubled,

F= 2(m1.m2)

(2d)^2

F= 2m1.2m2

4d^2
