    The value equal to the velocity of light in vacuum is

    A) \[\frac{\sqrt{{{\mu }_{0}}}}{{{\varepsilon }_{0}}}\]                                          

    B) \[\frac{1}{\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}}\]

    C) \[\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}\]                                           

    D) \[\sqrt{\frac{{{\mu }_{0}}}{{{\varepsilon }_{0}}}}\]

    Correct Answer: B

    Solution :

                     The velocity of light in vacuum is given by\[c=\frac{1}{\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}}\]where\[{{\mu }_{0}}\]and\[{{\varepsilon }_{0}}\]are respectively the absolute permeability and absolute permittivity of free space.
