STANDARD Physics Mutual Inductance MCQ Question
Type: MCQ-conceptual-Medium-Class 12
A short solenoid of radius a, number of turns per unit length n₁, and length L is kept coaxially inside a very long solenoid of radius b, number of turns per unit length n₂. What is the mutual inductance of the system?
A
μ₀πb²n₁n₂L
B
μ₀πa²n₁n₂L²
C
μ₀πa²n₁n₂L
D
μ₀πb²n₁n₂L²
Correct Answer
Option C
Detailed Explanation
The mutual inductance of the system is M = μ₀πa²n₁n₂L. This is derived from the formula for mutual inductance considering the geometry and arrangement of the solenoids.
