    The resistance and inductance of a coil are 1 ohm and 2 Henry respectively. A capacitor of \[2\mu F\] capacitor is discharged through the above coil. The frequency (n) and quality factor (Q) of L-C circuit will be:

    A) \[59,5Hz,{{10}^{3}}\]    

    B) \[69,5Hz,{{10}^{3}}\]

    C) \[79,5Hz,{{10}^{3}}\]    

    D) \[35,5Hz,{{10}^{2}}\]

    Correct Answer: C

    Solution :

    \[\sqrt{26}\]                 \[\Rightarrow \,\,1+{{a}^{2}}>0\] \[a\in R\] and \[\therefore \]
