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.

Plate M will be positively charged

Plate N will be positively charged

Both plates will be similarly charged

no charge will be collected on paltes.

Text Solution

Verified by Experts

The correct Answer is:

Consider the force on an electron in PQ. This electron experiences a force towards Q. Free electron in PQ tend to move toward N. So M will be positively charged.
