    The natural frequency of the circuit is:

    A) 159.24 Hz                     

    B) 200.12 Hz

    C) 110.25 Hz                     

    D) 95 Hz

    Correct Answer: A

    Solution :

    (a) 159.24 Hz Frequency, \[v=\frac{1}{2\pi \sqrt{LC}}\] \[=\frac{1}{2\pi \sqrt{20\times {{10}^{-3}}\times 50\times {{10}^{-6}}}}\] \[=\frac{{{10}^{3}}}{2\pi }=159.24\,Hz\]
