    The unit of expression\[{{\mu }_{0}}{{\varepsilon }_{0}}\]is

    A)  \[m\text{/}s\]                                 

    B)  \[{{m}^{2}}/{{s}^{2}}\]

    C)  \[{{s}^{2}}\text{/}{{m}^{2}}\]                                   

    D)  \[s\text{/}m\]

    Correct Answer: C

    Solution :

                    Velocity of light, \[c=\frac{1}{\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}}\] or                     \[{{\mu }_{0}}{{\varepsilon }_{0}}=\frac{1}{{{c}^{2}}}\]                                    \[=\frac{1}{{{(m\text{/}s)}^{2}}}\]                                    \[={{s}^{2}}\text{/}{{m}^{2}}\]
