Q. 664.0( 6 Votes )

Two particles are places at some distance from each other. If, keeping the distance between them unchanged, the mass of each of the two particles is doubled, the value of gravitational force between them will become:

A. 1/4 times B. 1/2 times

C. 4 times D. 2 times

Answer :

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

Now after keeping the d same and doubling the masses as 2m and 2M respectively, we get:

F’ = G * 2M * 2m/d2

F’ = 4 (G * M * m/d2)

F’ = 4F
