A parallel-plate capacitor has charge of magnitude 9.00μC on each plate and capacitance 3.00μF when there is air between the plates. The plates are separated by 2.00 mm. With the charge on the plates kept constant, a dielectric with (kappa = 5) is inserted between the plates, completely filling the volume between the plates.
