A long solenoid of diameter `0.1 m` has `2 xx 10^(4)` turns per metre. At the centre of the solenoid, a `100-`turns coil of radius `0.01 m` is placed with its axis coinciding with the constant rate from `+ 2 A` to `2 A` in `0.05 s`. Find the total charge (in `mu C`) flowing through the coil during this time when the resistance of the coil is `40 !=^(2) Omega`.
