Show that if the earth attracts two bodies, A and B placed at the same distance from the centre of the earth with the same force, then their masses are equal

Expert Answer:

let them be separated from earth at a distance of r each having masses as Ma and Mb
and masss of earth be Me
thus force between A and earth: Fea = GMeMa/r2
and force between B and earth: Feb = GMeMb/r2
thus Fea = Feb
hence Ma = Mb
