Question

How does polarised dielectric modify the original external field?

Answer 1

Answer:

when a dielectric is placed an electric field is set up between the plates of the capacitor, in a direction opposite to the electric frield which was there before placing the dielectric. ... the dielectric gets polarised due to induction and hence because of polarisation of the dielectric electric field is reduced overall.

Answer 2

☆$\red {HELLO\:DEAR}$☆

• This surface charges produce a field opposite to the external field.
• this surface charge densities on the either sides of the plate is produced.
• the dielectric gets polarised due to induction and hence because of polarisation of the dielectric electric field is reduced overall.
