Consider two solid dielectric spheres of radius a a separated by a distance R( R≫a). One of the spheres has a charge q and the other is neutral. We scale up the linear dimensions of the system by a factor of two. How much charge should reside on the first sphere now so that the force between the spheres remains the same?
