Question

The internal electric field produced by the bound charges in a polarised dielectric slab:

पर्याय

• Is zero everywhere inside the slab

• Is perpendicular to the external field

• Opposes the external field

• Reinforces the external field

Answer 1

The induced bound charges on the opposite faces of the slab produce an internal electric field that opposes the external field. This opposition reduces the resultant field inside the dielectric below the applied external field.
