An L-C circuit contains 196 pF capacitor and a 441 H inductor. The frequency of electromagnetic radiation emitted by antenna coupled to the L-C circuit is

Options

  1. A7.96 10^5 ~Hz
  2. B54.1 10^5 ~Hz
  3. C79.6 10^5 ~Hz
  4. D5.41 10^5 ~Hz

Correct answer

D. 5.41 10^5 ~Hz

Step-by-step solution

Given, capacitance, C=196 pF =196 10⁻¹² ~F Inductance, L=441 H =441 10⁻⁶ H Since, frequency, f= 1 2 L C aligned f & = 1 2 441 10⁻⁶ 196 10⁻¹² & = 1 2 14 21 10⁻⁹ & =5.41 10^5 ~Hz aligned
