Q. If $\mu_{0}$ is permeability of free space and $\varepsilon_{0}$ is permittivity of free space, the speed of light in vacuum is given by
A) $\sqrt{\mu_{0}\varepsilon_{0}}$
B) $\sqrt{\frac{\mu_{0}}{\varepsilon_{0}}}$
C) $\sqrt{\frac{1}{\mu_{0}\varepsilon_{0}}}$
D) $\sqrt{\frac{\varepsilon_{0}}{\mu_{0}}}$
Explanation
(c) The speed of light in vacuum is given by$\sqrt{\frac{1}{\mu_{0}\varepsilon_{0}}}$ , where $\mu_{0}$ is permeability and $\varepsilon_{0}\ $is permittivity of free space.
