A parallel plate capacitor of capacitance 7.6 µF has the space between the plates filled with a slab of glass with ? = 3.2. The capacitor is charged by attaching it to a 1.6-V battery. After the capacitor is disconnected from the battery, the dielectric slab is removed.
a) Find the capacitance after the glass is removed.
b) Find the charge on the plates after the glass is removed.
c) Find the energy stored in the capacitor after the glass is removed.
