Two metal spheres, each of radius 2.0 cm, have a center-to-center separation of 3.30 m. Sphere 1 has charge +1.10 10^-8 C. Sphere 2 has charge of -3.60 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.
