उत्तर १

Net dipole moment per unit volume induced in dielectric is called polarization. It is represented by P.
P = χe
P = Polarisation
 χe → Electrical succeptibility 
E = External electric field.

उत्तर २


Dipole moment per unit volume of a polarized dielectric is known as the polarization of a dielectric. It is denoted by the letter P for the linear isotropic dielectric. 

The polarisation of a linear isotropic dielectric,`"P" = "x"epsilon_@"E"` 
Where E is the net electric field from the effects of both free and bound charges.
