Let  \varepsilon _0  denote the permittivity of vacuum, the dimensional formula of the ε0 is  let M = Mass, L = length, T = time and I = electric current. Then

Detailed Solution for Electric Field And Potential MCQ Level - 1 - Question 1

Using Coulomb law, F = 1/4πϵ0(q1q2/R2)

⇒ϵ0 = q1q2/4πFR2

Substituting the units in the equation:

So, ϵ0 = C2/N.m2

=[AT]2/MLT-2.L2

 [∈0]=[M-1L-3T4A2]
