Question

The gravitational force between two bodies is 4 N.
What will be the gravitational force between the bodies
if the distance between them doubles?​

Answer 1

we know F=  Gm1m2/d^2

since the masses of the bodies are constant, if you double the distance then for the second force d'=2d

then F' =Gm1m2/(2d)^^2

            =Gm1m2/4d^2

            =1/4(Gm1m2/d20

            =1/4 F

            =1/4*4

            =1 N

so the existing force when you double the distance will be 1 N
