electron mass

\mathrm{m}

, speed of light in vacuum

\mathrm{c}

and Planck's constant

\mathrm{h}

are taken as fundamental quantities, the permeability of vacuum

\mu_0

can be expressed in units of

View answer and explanation

Correct option: C

\left(\frac{\mathrm{h}}{\mathrm{ce}^2}\right)

Option C

\left(\frac{\mathrm{h}}{\mathrm{ce}^2}\right)

is correct because dimensional analysis confirms that the permeability of vacuum can be expressed in these units.
