Question

when a dielectric substance is placed in an external field then electric torque is act upon the molecules and the molecules of dielectric substance arranged in the direction of electric field​

Answer 1

Explanation:

The molecules in the wood acquire an electric dipole moment in the direction of the external electric field.

Answer 2

Answer:

A dielectric gets polarized when it is placed in an electric field. The field produced due to the polarization minimizes the effect of external field. Hence, the electric field inside a dielectric decreases when placed in an external electric field..
