Answer 2

Answer:

Dimensional formula for magnetic permeability μ is [MLT−2A−2].

Permeability is the inductance per unit length. In SI units, permeability is measured in henries per metre (H/m = J/(A2⋅m) = N/A2). The auxiliary magnetic field H has dimensions current per unit length and is measured in units of amperes per metre (A/m).

You can see that the formula for permittivity and permittivity of free space is the same. So, the unit of permittivity of free space = A2s4Kg−1m−3 = Fm−1. Having the same formula as permittivity, the dimension of permittivity of vacuum is also [M−1A2T4L−3].
