Two metal spheres, each of radius 3.1 cm, have a center-to-center separation of 2.4 m. Sphere 1 has a charge of +1.4×10−8 C; sphere 2 has a charge of −3.7×10−8 C. 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). With V = 0 at infinity, calculate in volts (a) the potential at the point halfway between their centers and the potential on the surface of (b) sphere 1 and (c) sphere 2.
