    A capacitor when charged by a potential difference of 200 volt, stores a charge of 0.1 C. By discharging, energy liberated by the capacitor is :

    A) -30 J                                      

    B) -15 J

    C) 10 J                                                        

    D) 20J

    Correct Answer: C

    Solution :

    Given:\[V=200\]volt,\[Q=0.1\]coulomb Energy liberated \[U=\frac{1}{2}QV\] \[=\frac{1}{2}\times 0.1\times 200\] \[=10J\]
