    If \[V\] denotes the potential difference across the plates of a capacitor of capacitance \[C\], the dimensions of \[C{{V}^{2}}\]are                                          [CPMT 1982]

    A)             Not expressible in \[MLT\]      

    B)             \[ML{{T}^{-2}}\]

    C)             \[{{M}^{2}}L{{T}^{-1}}\]          

    D)             \[M{{L}^{2}}{{T}^{-2}}\]

    Correct Answer: D

    Solution :

                    \[\frac{1}{2}\,C{{V}^{2}}=\] Stored energy in a capacitor = \[[M{{L}^{2}}{{T}^{-2}}]\]
