What is the dimension of 1 _0 _0 ? ( _0= magnetic permeability and _0= permittivity of free space)

Question

Accepted Answer

Correct answer: A. (a) In free space, speed of EM wave is given by c= 1 _0 _0 ⇒c^2= 1 _0 _0 ⇒ Dimensions of 1 _0 _0= (c^2 )= ( LT^-1 )^2= (L^2T^-2 )

$What is the dimension of \frac{1}{μ _{0} ϵ _{0}} ? (μ_{0} = magnetic permeability and ϵ_{0} = permittivity of free space)$
