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: When I ¹ 0 and I' ¹ 0 are in the same direction, then two coil tend to move apart
