What is the relation between permittivity of free space and permeability of free space? (C is speed of light in vacuum).
1
\(C=~\frac{1}{\sqrt{{{\epsilon }_{0}}{{\mu }_{0}}}}\)
2
\(C=~\frac{{{\mu }_{0}}}{\sqrt{{{\epsilon }_{0}}}}\)
3
\(C=~\frac{{{\epsilon }_{0}}}{\sqrt{{{\mu }_{0}}}}\)
4
\(C=~\frac{1}{\sqrt{{{\epsilon }_{0}}/{{\mu }_{0}}}}\)
