Question

If the distance between the two spherical bodies is increased to two times, then by how many
times, the mass of one of the bodies to be changed to maintain the same gravitational force?​

Answer 1

If the distance is increased by 2 times ,then

F = GMm/r²

F = GMm/ (2r)²

F = GMm/4r²

So as to maintain the same gravitational force the mass of one of the bodies should be increased by 4times

Now,

F = G4Mm/4r²

F = GMm/r²

here, 4 cancels 4 and thus the force remains same.
