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.
