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