Remembering +4 | -1

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

View answer and explanation

Correct option: C

\sqrt {\frac{1}{{{\mu _0}{\varepsilon _0}}}}

Option C (

\sqrt {\frac{1}{{{\mu _0}{\varepsilon _0}}}}

) is correct because the speed of light in vacuum is given by

c = \frac{1}{\sqrt{{\mu_0 \varepsilon_0}}}

.
