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.

Two charged conducting spheres of radii a and b are connected to each other by a wire. What is the ratio of electric fields at the surfaces of the two spheres? Use the result obtained to explain why charge density on the sharp and pointed ends of a conductor is higher than on its flatter portions.

A solid conducting sphere having a charge Q is surrounded by an uncharged concentric hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be v. If the shell is now given a charge of -3 Q, the new potential difference between the same two surfaces is _____.
