A capacitor of C1, whose area is A1 and distance between the places is d, is connected to a battery V1. When the capacitor is completely charged, a dielectric material of k1 is inserted into the material. Now the battery is disconnected and the distance between the plates is doubled.
a. What will happen to the voltage? Will it increase or decrease? Show the work.
b. If a quartz dielectric is inserted into a charged parallel-plate capacitor, by what factor will the energy stored in the capacitor change?
