The value of mutual inductance of two co...

The value of mutual inductance of two coils is B 10 mH. If the current in one of the coil changes from 5A to 1A in 0.2 s, calculate the value of emf induced in the other coil. Also calculate the value of induced charge passing through thecoil if its resistance is 5 ohm.
