        An L-C circuit is in the state of resonance. If \[C=0.1\text{ }\mu F\]and\[L=0.25\text{ }H\]. Neglecting ohmic resistance of circuit. What is the frequency of oscillations?

    A)  1007 Hz               

    B)  100 Hz

    C)  109 Hz                                 

    D)  500 Hz

    Correct Answer: A

    Solution :

                    From the formula, the frequency of oscillation is \[f=\frac{1}{2\pi \sqrt{LC}}\] \[=\frac{1}{2\pi \sqrt{0.25\times 0.1\times {{10}^{-6}}}}\] \[=1007\text{ }Hz\]
