every volume element Dv of the slab has a dipole moment
P Dv in the direction of the field The volume element Dv  is
macroscopically small but contains a very large number of
molecular dipoles Anywhere inside the dielectric, the
volume element Dv has no net charge (though it has net
dipole moment) This is, because, the positive charge of one
dipole sits close to the negative charge of the adjacent dipole
