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 `K_(1)` is closed and `K_(2)` remains open, the charges on the surfaces a,b,c,d,e and f will be respectively.A. `0, -Q,Q,0,0` and `0`B. `0,-Q//2,Q//2,Q//2` and `0`C. `0,-Q//3,Q//3,2Q//3,-2Q//3` and `0`D. `-Q//3,Q//3,2Q//3,-2Q//3,-Q//3` and `Q//3` |
