A parallel-plate capacitor has square plates that are 8.20 cm on each side and 4.80 mm apart. The space between the plates is completely filled with two square slabs of dielectric, each 8.20 cm on a side and 2.40 mm thick. One slab is Pyrex glass and the other slab is polystyrene. If the potential difference between the plates is 88.0 V, find how much electrical energy (in nJ) can be stored in this capacitor.
