Question

Explain the polarization of a non-polar dielectric in an external electric field.

Answer 1

Answer:

please mark as brainliest

Explanation:

When non-polar molecules are subjected to an external electric field, the positive and negative charges in the molecules are displaced in the opposite direction. ... Thus nonpolar molecules acquire induced dipole moment in the external electric field and are said to be polarised in the external electric field.

Answer 2

Explanation:

If a dielectric (non-polar) molecule is placed in an external electric field, a small induced dipole moment is created because the positive charge in each atom is pushed in the direction of the field and negative charge is pushed in the opposite direction as shown in the figure.

Polarization is the amount of induced surface charge per unit area or the surface density of polarization charges appearing at right angles to applied external electric field.
