Mutual inductance between two coils is 4H. If the current in one coil ...
Given:
Mutual inductance (M) = 4H
Rate of change of current (di/dt) = 2 A/s

To Find:
EMF induced in the other coil

Formula:
EMF induced (e) = -M*(di/dt)

Calculation:
Substituting the given values in the formula,
e = -4 * 2 = -8V

Since EMF is a scalar quantity, the answer is positive,
e = 8V

Therefore, the EMF induced in the other coil is 8V.

Final Answer:
The correct option is (a) 8V.
