The gravitational force of attraction between two objects is x, Keeping the masses of the objects unchanged, if the distance between the objects is halved, then the magnitude of gravitational force between them will become:

A. x/4 B. x/2

C. 2x D. 4x

Answer :

We know, F = G * M * m/d2

Now after keeping the masses of the object constant and decreasing the distance between them to half, than the previous, we get:


F’ = G * M * m/ (d/2)2


F’ = 4 (G * M * m/d2)


F’ = 4F
