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.
