    The dimesions of \[\frac{1}{\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}}\] are:

    A)  \[[{{I}^{o}}{{M}^{o}}L{{T}^{-1}}]\]            

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

    C)  \[[{{I}^{-2}}{{T}^{-2}}LM]\]                 

    D)  \[2[{{I}^{o}}{{M}^{o}}{{L}^{-1}}T]\]

    Correct Answer: A

    Solution :

    It is the speed of light in vacuum and speed is the distance travelled in a certain time interval. Hence its dimensions will be \[[{{I}^{o}}{{M}^{o}}L{{T}^{-1}}]\]
