WebIf the electrical field in the dielectric is 1.5 MV/m, what are (a) the charge density on the capacitorplates, and (b) the induced charge density on the surfaces of the dielectric? Two flat plates containing equal and opposite charges are separated by material 4.0 mm thick with a dielectric constant of 5.0. WebINDUCED CHARGE AND POLARIZATION When a dielectric material is inserted between the plates while the charge is kept constant, the potential difference between the plates decreases by a factor K. Therefore the electric field between the plates must decrease by the same factor.
