But in fact while insulators don't allow charge to migrate freely, they do allow charges to displace slightly, and this affects the electric field within the substance.

Without dielectric, the charge on the plates is Q0=C0V0=(20.0pF)(40.0V)=0.8nC. Since the battery is disconnected before the dielectric is inserted, the plate charge is unaffected by the dielectric and remains at 0.8 nC.

However, to form a full system of equations necessary to solve electrostatics problems, they have to be complemented by certain constitutive relations between the vectors P and E.
