CBSE Class 12-science Answered
Why is the electric field in a capacitor after introduction of dielectric= (sigma -sigma p)/ epsilon .
Where sigma is surface charge density and sigma p is surface charge density of the polarised dielectric.

Expert Answer
Because the electric field polarizes the dielectric as a result charges are induced on the surface of the dielectric which induces electric field . But the induced electric field is in opposite direction to the original electric field E. Therefore the net electric field is given by
