by how much does value of gravitational force b\w two bodies decrease when distance between them is doubled?

Answer 1

It decreases to 1/4 of the original force. This is because the force of gravity is inversely proportional to the distance between the two bodies. Thus, increasing distance by a factor of n reduces force to 1/n^2.

Answer 2

Newton's inverse square law of gravitation

If the distance is doubled the force is reduced to 1/4

If the distance is tripled the force is reduced to 1/9

Answer 3

it is reduced by the inverse square of the distance and if doubled becomes 1/4 if tripled becomes 1/9 and if quadrupled becomes 1/16

1/d^2
