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 respectivelyA. `0,Q,-Q,0,0` and `0`B. `0,0,0,Q,-Q` and `0`C. `0,-2Q//3,2Q//3,Q//3,-Q//3` and `0`D. `0,-Q//3,Q//3,2Q//3,-2Q//3` and `0` |
