Two Conducting Spheres, a and B, Are Made of the Same

Multiple Choice

Two conducting spheres, A and B, are made of the same material and have radii r and 2r. The spheres are placed a distance d > 3r from each other. The first sphere has an initial charge Q, while the second is uncharged. The spheres are initially connected by a thin conducting wire; the wire is then removed. When electrostatic equilibrium has been reached, the magnitudes of the electric fields near the surfaces of the respective spheres are related by

A) E_A > E_B.
B) E_A = E_B.
C) E_A < E_B.
D) More information is needed to work out the answer.
