A. [M-1L-3T4I2]
B. [M-1L-3T4I4]
C. [M-1L-3T2I2]
D. [M1L-3T4I2]
Answer:A
The dimension of ?o _______
A. [M-1L-3T4I2] B. [M-1L-3T4I4] C. [M-1L-3T2I2] D. [M1L-3T4I2]
Explanation: ?o is the absolute permittivity of air medium and has 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.
