An air gap capacitor having a capacitance of 2.00μF is connected to a battery; it acquires a charge of 6.00μC. The battery is then disconnected. (Assume that, to a good approximation, the formulas for an infinite parallel plate capacitor apply.) A neutral insulating sheet with a dielectric constant of 2.5 is inserted between the plates of the charged capacitor, completely filling the gap. What is the capacitance of the capacitor now that the insulator has been added?

A capacitor has a capacitance of 49 micro-farads without a dielectric while connected to a 20 volt battery. Then the distance between the plates is decreased by a factor of 5 and a dielectric with a dielectric constant of 2.29 is inserted between the plates of the capacitor while still connected to the same battery. What is voltage, in volts, across the capacitor after the dielectric and the distance between the plates have been changed?
