NEET 2022 Physics, question 37

Question 37 of the NEET 2022 paper (code R1) is a Physics question from Alternating Current. Its idea, Resonant Frequency Condition, was asked twice, in 2022 and 2023, across NEET 2017–2026. The NTA final answer key gives option 3.

Q37 · Physics

A series LCR circuit with inductance 10 H, capacitance 10 μF, resistance 50 Ω is connected to an ac source of voltage, V = 200 sin(100 t) volt. If the resonant frequency of the LCR circuit is νo\nu_o and the frequency of the ac source is ν\nu, then :

  1. 1ν\nu = 100 Hz ; νo=100π\nu_o = \frac{100}{\pi} Hz
  2. 2νo=ν\nu_o = \nu = 50 Hz
  3. 3νo=ν=50π\nu_o = \nu = \frac{50}{\pi} HzOfficial answer
  4. 4νo=50π\nu_o = \frac{50}{\pi} Hz, ν\nu = 50 Hz
