Question
How does the electric field inside a dielectric decrease when it is placed in an external electric field?
✓

Answer

When a dielectric is placed in an external electric field, the charges are induced on the faces of dielectric which produce opposite electric field in the dielectric. Thus net electric field inside the dielectric is reduced.
