Question

What is the stated value of the permittivity of free space?

Options

• \[8.85\times10^{-12}\,\mathrm{C^2N^{-1}m^{-2}}\]

• \[3\times10^6\,\mathrm{C^2N^{-1}m^{-2}}\]

• \[8.85\times10^{-12}\,\mathrm{V/m}\]

• \[8.85\times10^{12}\,\mathrm{C^2N^{-1}m^{-2}}\]

Answer 1

The permittivity of free space is denoted by \[\varepsilon_0\]. Its stated value is \[8.85\times10^{-12}\,\mathrm{C^2N^{-1}m^{-2}}\].
