When a dielectric slab is placed in a uniform electric field (between a capacitor) say Eo, the extreme faces of the dielectric slab get induced and the face near the positive plate of a capacitor gets negatively charged, the face near the other plate gets positively charged, the in between atoms are neutral. Okay, then the electric field inside the dielectric is E=Eo-Ep. But the induced charges on the extreme faces, will they not change the electric field between the corresponding plate and faces? I mean my sir said that the electric field between the two faces and the plates will remain Eo. How is this possible? Will the induced charges on the faces not slightly change the electric field?
