What will be the permittivity of a medium which has a dielectric constant of 5.4?
a) 4.78*10-11 C2N-1m-2
Explanation: εo=8.854*10-12C2N-1m-2. Therefore the permittivity will be 5.4*8.854*10-12C2N-1m-2 = 4.78*10-11C2N-1m-2. We know that the permittivity of a medium is equal to its relative permittivity multiplied by the absolute permittivity of air. Air has relative permittivity =1.
