NEET Physics Resonance Assertion Reason Question
Assertion (A): A metal detector works based on the principle of resonance in an AC circuit. | Reason (R): The resonant frequency in a metal detector is adjusted by varying the inductance of the coil.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
The assertion is true as metal detectors operate on the principle of resonance in AC circuits, but the reason is false because the resonant frequency is adjusted by varying the capacitance, not the inductance.
