    The dimensional formula for emf \[\varepsilon \] in MKS system will be:

    A)             \[[M{{L}^{2}}{{T}^{-3}}{{A}^{-1}}]\]                 

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

    C)             \[[M{{L}^{2}}A]\]       

    D)             \[[ML{{T}^{-2}}{{A}^{-2}}]\]

    Correct Answer: A

    Solution :

    (a) \[[M{{L}^{2}}{{T}^{-3}}{{A}^{-1}}]\]                         \[\varepsilon =\frac{[W]}{[q]}=\frac{M{{L}^{2}}{{T}^{-2}}}{AT}=M{{L}^{2}}{{T}^{-3}}{{A}^{-1}}\]
