If the dielectric constant of a substance is $K = \frac{4}{3}$,then the electric susceptibility $\chi_{e}$ is

$A$ cube of side $1 \ cm$ contains $100$ molecules,each having an induced dipole moment of $0.2 \times 10^{-6} \ C \cdot m$ in an external electric field of $4 \ N \cdot C^{-1}$. The electric susceptibility of the material is .... $C^2 \cdot N^{-1} \cdot m^{-2}$.

The dielectric constant $K$ of an insulator cannot be

Polar molecules are the molecules:

If the dielectric constant and dielectric strength are represented by $k$ and $x$ respectively,what properties should a suitable material have to be used as a dielectric in a capacitor?

The dielectric constant for a metal is
