Question

what is dimensional formulae for permittivity of free space

Answer 1

Answer: [M⁻¹L⁻³T⁴A²]  is dimensional formulae for permittivity of free space indicated by ∈₀ .

Answer 2

Permittivity =[Ɛo] = [Charge]² /([Force] [Distance]²) =[TA]² / [MLT^(-2)] [L]² {[A] is the dimensional formula of electric charge} =[TA]2 / [ML3T-2] =[M-1L-3T(2+2)A2] = [M-1L-3T4A2].
