Question

The force of attraction between two bodies is 20 N. Calculate the force between them when mass of each body as well as the distance between them are halved

Answer 1

The initial force b/n two bodies F=Gmm/r^2 eq-1 If distance and masses are halved then we get F*=G(m/2)(m/2)/(r/2)^2p eq-2 eq-1/eq-2 we get F/F*=1 Therefore we get F=F*
