    A LC circuit is in the state of resonance. If \[C=0.1\mu F\] and \[L=0.25\]henry. Neglecting ohmic resistance of circuit what is the frequency of oscillations  [BHU 2003; MP PMT 2005]

    A)            1007 Hz                                   

    B)            100 Hz

    C)            109 Hz                                     

    D)            500 Hz

    Correct Answer: A

    Solution :

               \[{{\nu }_{0}}=\frac{1}{2\pi \sqrt{(0.25)\times (0.1\times {{10}^{-6}})}}=\frac{{{10}^{4}}}{9.93}=1007\,Hz\]
