Two metal spheres, each of radius 2.0 cm, have a center-to-center separation of 2.7 m. One has a charge of +1.0 ✕ 10-8 C; the other has a charge of -3.7 ✕ 10-8 C. Assume that the separation is large enough relative to the size of the spheres to permit us to consider the charge on each to be uniformly distributed (the spheres are electrically isolated from 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.
