A parallel-plate capacitor is constructed of plates with area
2.5 m2 that are separated by 0.5 mm of air (dielectric constant Ka
= 1:0006). The capacitor is connected to a 9 V battery and fully
charged. The battery is then disconnected, and quartz is inserted
to ll the gap between the plates (dielectric constant Kq = 4:3).
Determine whether the energy density of this capacitor increased or
decreased when the quartz was inserted, and by how much.
