Q.

A square metal wire loop of side 10cm and resistance 1Ω is moved with a constant velocity v0 in a uniform magnetic field of induction B = 2 Weber/m2 as shown in the figure. The magnetic field lines are perpendicular to the plane of the loop (directed into the paper). The loop is connected to a network of resistors each of value 3Ω. The resistances of the lead wires OS and PQ are negligible. What should be the speed of the loop so as to have a steady current of 1 mA in the loop
