Question

What is electrostatic shielding?

Options

• The movement of charge from a conductor to the ground.

• The phenomenon in which the electric field inside a cavity of a conductor is zero, irrespective of external charges or fields.

• The condition in which charges in a conductor are at rest.

• The charge per unit area on the surface of a conductor.

Answer 1

Electrostatic shielding refers to a zero electric field inside a conductor's cavity, regardless of external charges or fields. The stated condition applies when no charge is placed inside the cavity.
