Question

what happened to the gravitational force between two object of masses of both infect are doubled and distance between them is also doubled​

Answer 1

The gravitational force will remain same

Solution

Let m1 and m2 be a present masses , r1 be a distance between them and F1 be force of attraction between that two objects

Then gravitational force become

F1=Gm1.m2/r^2

In second case let M1 and M2 be mass of a objects when it gets double and R be distance and force between them is F2

Then F2=GM1.M2/R^2

Since

M1=2m1

M2=2m2

R=2r then

F2=G2m1.2m2/(2r)^2

F2=4Gm1.m2/4r^2

F2= Gm1.m2/r^2

F1 =F2

I hope it will help
