Question

The main response of a dielectric to an external electric field is:

Options

• Charge redistribution on the surface

• Induced or aligned dipoles inside the material

• Complete cancellation of the external field outside the material

• Rapid flow of free charge carriers through the bulk

Answer 1

For a dielectric, the main response to an external field is the formation of induced or aligned dipoles inside the material. Charge redistribution on the surface is the main response of a conductor instead.
