Answer :

(a) (i) CONDUCTOR


= external field


= internal field created by the redistribution of electrons inside the metal.


When a conductor like a metal is subjected to external electric field, the electrons experience a force in the opposite direction collecting on the left hand side.


A positive charge is therefore induced on the right hand side. This creates an opposite electric field () that balance out

The net electric field inside the conductor becomes zero.


(iii) DIELECTIRC:

When external electric field is applied, dipoles are created (in case of non-polar dielectrics). The placement of dipoles is as shown in the given figure. An internal electric field is created which reduces the external electric field.
Polarization of dielectric (P) is defined as the dipole moment per unit volume of the polarized dielectric.

Where, = susceptibility and E= electric field.


(b) Net force on the charge, placed at the centre of the shell, is zero.


Force on change 2Q kept at a point A


F=E× 2Q=


Electric flux through the shell,
