SSC SSC JE Electrical 2025 Mock Test Series (Paper 1 & Paper 2) Physics Electromagnetic Induction and Inductance Mutual Induction
Two long solenoids S1 and S2 have equal lengths and the solenoid S1 is placed co-axially inside the solenoid S2. The ratio of the radius of the solenoid S1 and S2 is 1 : 2. If the mutual inductance of the solenoid S1 due to solenoid S2 is 4 H, then the mutual inductance of the solenoid S2 due to solenoid S1 will be:
1
4 H
2
8 H
3
2 H
4
None of these
