NEETPhysicsElectromagnetic InductionMCQ+4 / −1
A long solenoid of diameter 0.1 m has 2 ×\times× 104 turns per meter. At the centre of the solenoid, a coil of 100 turns and radius 0.01 m is placed with its axis coinciding with the solenoid axis. The current in the solenoid reduces at a constant rate to 0 A from 4 A in 0.05 s. If the resistance of the coil is 10 π\piπ2 Ω\OmegaΩ, the total charge flowing through the coil during this time is
