    An \[LC\] circuit is in the state of resonance. If C = 0.1  \[\mu F\]and L = 0.25 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 \[f=\frac{1}{2\pi \sqrt{LC}}\] \[=\frac{2}{2\pi \sqrt{0.25\times 0.1\times {{10}^{-6}}}}=1007\,Hz\]
