Two metal spheres, each of radius 4.0 cm, have a center-to-center separation of 4.00 m. Sphere 1 has charge +2.30 10-⁸ C. Sphere 2 has charge of -3.30 10-8C. Assume that the separation is large enough for us to assume that the charge on each sphere is uniformly distributed (the spheres do not affect each other). Take V = 0 at infinity.

(a) Calculate the potential at the point halfway between the centers.

(b) Calculate the potential on the surface of sphere 1.

(c) Calculate the potential on the surface of sphere 2.
