Two conducting spheres, one having twice the diameter of the other, are separated by a distance large compared to their diameters. The smaller sphere (1) has charge q and the larger sphere (2) is uncharged. If the spheres are connected by a long thin wire:

Question

Quizplus · Accepted Answer

When the spheres are connected by a wire, electrons will flow from the negatively charged sphere (1) to the neutral sphere (2) until they reach equilibrium. At equilibrium, the potential will be equal between the two spheres, meaning that choice A is correct. The size of the spheres does not affect the potential difference between them, only the amount of charge they can hold. Therefore, choices B, C, D, and E can be ruled out.
