When the dielectric is placed in an external electric field, the electric field inside the dielectric is
less than the external electric field.
larger than the external electric field.
equal to the external electric field.
equal to or greater than external electric field.
Solution
Dipole moment will be in same direction as the external field. The collective effect of dipole moment produces a field that opposes the electric field inside the dielectric and hence, the net electric field inside the dielectric is less than external electric field.
