Two solid metal spheres of different radii are far apart. The spheres are connected by a fine metal wire. Some charge is placed on one of the spheres. After electrostatic equilibrium is reached, the wire is removed. Which of these quantities will be the same for the two spheres?

(a) The charge on each sphere
(b) The electric field inside each sphere, at the same distance from the center of the spheres
(c) The electric field just outside the surface of each sphere
(d) The electric potential at the surface of each sphere
(e) Both (b) and (c)
(f) Both (b) and (d)
(g) Both (a) and (c)
