A long wire AB is placed on a table. Another wire PQ of mass 1.0 g and length 50 cm is set to slide on two rails PS and QR. A current of 50A is passed through the wires. At what distance above AB, will the wire PQ be in equilibrium
Text Solution
Verified by ExpertsThe correct answer is:
A
Suppose in equilibrium wire PQ lies at a distance r above the wire AB
Hence in equilibrium mg
