NEET Physics Resonance MCQ Question

Type: MCQ-numerical-Hard-Class 12

In a series RLC circuit, what is the resonant frequency f0f_0 if the inductance LL is 0.2 H and the capacitance CC is 50 μF\mu F?

A

50.3 Hz

B

159.2 Hz

C

112.5 Hz

D

71.1 Hz

Correct Answer

Option B

Detailed Explanation

The resonant frequency f0f_0 is given by f0=12πLCf_0 = \frac{1}{2\pi\sqrt{LC}}. Substituting L=0.2L = 0.2 H and C=50μFC = 50 \mu F, we get f0159.2f_0 \approx 159.2 Hz.
