The figure shows three identical parallel conducting plates X, Y and Z. The separation between X and Y is 2d, and that between Y and Z is d. The six surfaces of the three plates are labeled a, b, c, d, e and f, as shown. The key K1 can connect X to ground, and the key K2 can connect Z to ground. Initially, both keys are open. Y has Q charge; X and Z have no charge.If K2 is closed and K1 remains open, the charges on the surfaces a, b, c, d, e and f will be respectively (a) 0, 0, 0, Q, –Q and 0 (b) 0, -Q/3, Q/3, 2Q/3, -2Q/3 and 0 (c) 0, -2Q/3, 2Q/3, Q/3, -Q/ 3 and 0 (d) -Q/3, Q/3, Q/3, 2Q/3, -Q/3 and Q/3 |
