Question

The correct relation for dielectric medium is

Answer 1

Hope!!!!!
Its help u.........

Answer 2

Answer: The correct answer is $k=\frac{\epsilon _{r}}{\epsilon _{0}}$.

Explanation:

Dielectric constant: It is the property of an electrical insulating material. It is a poor conductor of electricity.

The force between two electric charges in dielectric charges in dielectric medium which is less than in vacuum.

It has no unit.

The mathematical formula for the dielectric constant is as follows;

$k=\frac{\epsilon _{r}}{\epsilon _{0}}$

Here, $\epsilon _{r}$ is the permittivity of medium, $\epsilon _{0}}$ is the permittivity of free space and k is the dielectric constant.
