Consider two conducting spheres of radii of `R_1` and `R_2` with `R_1 > R_2`. If the two are at the same potential the larger sphere has more charge than the smaller spheres. State whether the charge density of the smaller sphere is more or less than that of the larger one.

A and B are two conducting spheres of the same radii. A being solid and B hollow. Both are charged to the same potential. What will be the relation between the charges on the two spheres?
