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 193 volt battery is connected to a 0.3 microfarad parallel-plate capacitor with air between the plates. Now the battery is disconnected, with care taken not to discharge the capacitor. Some paper is then inserted between the plates completely filling up the space. What is the final potential difference between the plates ? (the dielectric constant for air is = 1 and for the paper inserted is = 3)
