Capacitors: Practice Problem & Solution

Polar molecules are the molecules: (2021)
Acquire a dipole moment only in the presence of electric field due to displacement of charges.
Acquire a dipole moment only when magnetic field is absent.
Having a permanent electric dipole moment.
Having zero dipole moment.

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Capacitors. Understanding the underlying formula is key to arriving at the correct answer below:

In polar molecules, the centers of positive and negative charges do not coincide due to asymmetric charge distribution. This inherent separation of charges gives them a permanent electric dipole moment even without an external field.
