Two conducting spheres, one having twice the diameter of the other, are separated by a distance that is large compared to their diameters. The smaller sphere has charge q and the larger sphere is uncharged. If the spheres are connected by a long, thin wire, then after a sufficiently long time:
a. The two spheres are at the same potential.
b. The electric field at the surface of the two spheres has the same magnitude.
c. The two spheres have the same charge.
d. The larger sphere is at twice the potential of the smaller sphere.
e. The smaller sphere is at twice the potential of the larger sphere.
