1.	A rod `PQ` is connected to the capacitor plates. The rod is placed in a magnetic field `(B)` directed downwards perpendicular to the plane of the paper. If the rod is pulled out of magnetic field with velocity `vec(v)` as shown in Figure. A. Plate `M` will be positively chargedB. Plate `N` will be positively chargedC. Both plates will be similarly chargedD. no charge will be collected on plates.
Answer» Correct Answer - A Consider the force on n electron in `PQ`. This electron experiences a force towards `Q`. Free electron in `PQ` tend to move towards `N`. So `M` will be positively charged.
