Question

Two coils P and Q are placed co-axially and carry current I and I' respectively

If I' = 0 and P moves towards Q, a current in the same direction as I is induced in Q
If I = 0 and Q moves towards P, a current opposite in direction to that of I' is induced in P
When I ¹ 0 and I ' ¹ 0 are in the same direction, then two coil tend to move apart
None of these

The correct answer is: If I = 0 and Q moves towards P, a current opposite in direction to that of I' is induced in P
