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?
