[Solved] The dimension of εo ____ (MCQ)

The dimension of εo _______

a) [M-1L-3T4I2]
b) [M-1L-3T4I4]
c) [M-1L-3T2I2]
d) [M1L-3T4I2]

Answer: a
Explanation: εo is the absolute permittivity of air medium and has a value 8.854*10-12C2N-1m-2. Its dimension is [M-1L-3T4I2]. The permittivity of a medium is the product of this term with the dielectric constant or relative permittivity of that medium.
