A parallel plate capacitor has a capacitance of Co = 5.40 pF when there is air between the plates. The separation between the plates is 1.50 millimeter.
a.) Find the maximum magnitude of charge that can be placed on every plate if the electric field in the region between the plates is not to exceed 3.00×104 V/m?
b.) A dielectric with a dielectric constant of 3.20 is inserted between the plates of the capacitor, completely filling the volume between the plates. Now what is the maximum magnitude of charge on every plate if the electric field between the plates is not to exceed 3.00×104 V/m?
