Question
Let [ε0] denote the dimensional formula of the permittivity of the vacuum and [μ0] that of the permeability of the vacuum. If M = mass, L= length, T = time and I = electric current.
Options
A.[ε0] =[M-1L-3T-2I]
B.[ε0] =[M-1L-3T4I2]
C.[μ0] =[MLT-2I-2]
D.[μ0] =[ML2T-1I]
Solution
F = 
ε0 =
= [M-1L-3T4I2]
Speed of light, c =
∴ [μ0 =
=
= [MLT-2I-2]
ε0 =
= [M-1L-3T4I2]Speed of light, c =
∴ [μ0 =
=
= [MLT-2I-2]Create a free account to view solution
