The following information from Problem 2 is provided to help with answering Problem 3 The plates of a parallel plate capacitor each have an area of 0.40 m2 and are separated by a distance of 0.02m. They are charged until potential difference between the plates is 3000 V. The charged capacitor is then disconnected from the battery. Suppose that a dielectric sheet is inserted to completely fill the space between the plates and the potential difference between the plates drops...
