AB and CD are fixed conducting smooth rails placed in a vertical plane and joined by a constant current source at its upper end. PQ is a conducting rod which is free to slide on the rails. A horizontal uniform magnetic field exists in space as shown. If the rod PQ is released from rest then,
Text Solution
Verified by ExpertsThe correct answer is:
D
It the magnitude of I A is very large such that force due to magnetic field on PQ exceeds its weight then it will move upwards otherwise it will move downwards.
