    \[\left[ M{{L}^{2}}{{T}^{-3}}{{I}^{-1}} \right]\]is the dimension of

    A)  electric field                     

    B)  capacity

    C)  potential                            

    D)  permittivity

    Correct Answer: C

    Solution :

                     We know that                 Potential \[V=\frac{energy\,\left( Q \right)}{charge\text{ }\left( q \right)}\] Dimensions of energy \[(Q)=[M{{L}^{2}}{{T}^{-2}}]\] Dimensions of charge (q) = [IT] \[\therefore \] Dimensions of potential \[V=\frac{[M{{L}^{2}}{{T}^{-2}}]}{[IT]}\] Dimensions of potential \[V=[M{{L}^{2}}{{T}^{-3}}{{I}^{-1}}]\]
