Figure shows a circuit having a coil of resistance R = 2.5 Ω and inductance L connected to a conducting rod of radius 10 cm with its center at P.Assume that friction and gravity are absent and a constant uniform magnatic field of 5T exists as shown in figure. At t=0, the circuit is switched on and simultaneously a time-varying external torque is applied on the rod so that it rotates about P with a constant angular velocity 40rads−1. Find the magnitude of this torque (in mNm) when current reaches half of its maximum value. Neglect the self inductance of the loop formed by the circuit.

A long solenoid of diameter 0.1 m has 2 × 10 ^ 4 turns per metre. At the center of the solenoid, a 100-turn coil of radius 0.01 m is placed with its axis coinciding with the solenoid axis. The current in the solenoid is decreased at a constant rate from +2 A to – 2 A in 0.05 s. Find the total charge (in μC) flowing through the coil during this time when the resistance of the coil is 40 π ^ 2 Ω.
