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 K_(1) can connect X to ground,and the key K_(2) can connet Z to ground. Initially, both keys are open. Y has Q charge, X and Z have no charge. If both K_(1) and K_(2) are closed, the charges on the surfaces a,b,c,d,e and f will be respectively |
