A dielectric with non-polar molecules is kept in an external electric field
A dielectric with polar molecules is kept in an external electric field
A dielectric and a conductor are placed in an external electric field of magnitude Eext. The charge density induced at the surface of the dielectric and the conductor are σd and σe respectively.  The net electric field inside the dielectric and the conductor are Ed and Ec respectively. Then, 
A dielectric is placed in an electric field.
A dielectric is placed in an electric field E.
The external force acting on a non polar molecule due applied field  is countered by
A dielectric is placed in an electric field. The electric displacement is
The term Polarizability is defined as the
