Question

The molecules of a polar dielectric have no dipole moment. State true or false.

(a) True

(b) False

I got this question during an interview for a job.

This interesting question is from Dielectrics and Polarisation topic in division Electrostatic Potential and Capacitance of Physics – Class 12

Answer 1

The correct choice is (b) False

To explain: The molecules of a polar dielectric have permanent dipole moments. In the absence of an external electric field, the dipole moments of different molecules are randomly oriented due to thermal agitation in the material.
