Answer:
Explanation:
Permittivity of water = 81 x absolute permittivity
=81 x 8.85 x 10^-12
= 716.85 x 10^-12 c² /Nm²
Answer: The correct answer is 7.12 MKS unit.
Explanation:
The mathematical formula for the dielectric constant is as follows;
Here, is the absolute permittivity, is the permittivity of free space and K is the dielectric constant.
It is given in the problem that the dielectric constant of water is 81.
Calculate the absolute permittivity.
Put and K=81.
Therefore, the absolute permittivity is 7.12 MKS unit.
