Question

If [ε₀] represents the dimensional formula of permittivity of free space and mass = M, length = L and time = T, then.

(a) [ε₀] = [M^-1L^-3T²A¹]

(b) [ε₀] = [M^-1L^-3T⁴A²]

(c) [ε₀] = [M^-2L²T^-1A²]

(d) [ε₀] = [M^-1L²T^-1A²]

Answer 1

Since electrostatic force between two charges,

Hence; option (b) is correct.
