ElectroMagnetic InductionHard
Question
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 in released from rest then,
Options
A.The rod PQ will move downward with constant acceleration
B.The rod PQ will move upward with constant acceleration
C.The rod will move downward with decreasing acceleration and finally acquire a constant velocity
D.Either A or B
