Two point objects of mass 2x and 3x are separated by a distance r. Keeping the distance fixed mass should be transferred from 3x to 2x. so that gravitational force between them becomes maximum

Answer» F = K (3x - m) (2 x + m)     where K = G / R^2      and m is the mass transferreddF / DM =   K d (6 x^2 + x m - m^2) / dm = 0 to find maximumx - 2 m = 0       So     m = x / 2
