A long solenoid of diameter 0.1 m has turns per metre. At the centre 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 A in 0.05 s. Find the total charge (in ) flowing through the coil during this time when the resistance of the coil is |
