The unit of intensity of polarization is . . . . . . .

Why can a metal not be used as a dielectric in a capacitor?

Give examples of polar and non-polar molecules.

Define dielectric constant.

$A$ 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 .... $C^2 \cdot N^{-1} \cdot m^{-2}$.

Which of the following is the dimensional formula for electric polarisation?
