Two coils have a mutual inductance of 0.004 H. The current changes in the first coil according to equation , where = 10 A and = 50 rad s. The maximum value of e.m.f. in the second coil in volt is

Answer: (D)

Solution

The emf induced in the second coil is , so its maximum value is . With H, A: . All options are multiples of , so the
