Let ε0 denote the dimensional formula of the permittivity of the vacuum and  ε0 that of the permeability of the vacuum. If M= mass, L=length,T= time and I= electric current, then

a
ε0=M-1 L-3 T2I
b
ε0=M-1 L-3 T4I2
c
μ0=MLT-2 I-1
d
μ0=ML2 T-1I

detailed solution

Correct option is B

F=14πε0·q1q2r2 ϵ0=q1q2[F]r2=[1T]2MLT-2L2=M-1 L-3 T4I2Speed of light,c=1ε0μ0 ∴μ0=1ε0[c]2=1M-1L-3T4I2LT-12=MLT-2I-2
