Consider you have a square parallel-plate capacitor which has 6.00 cm lenght on each side. The spearation between parallel plates is 4.10 mm . You completely fill the capacitor with two different dielectric materials, each 6.00 cm on a side and 2.05 mm thick. Assume that one of the dielectric material is pyrex glass and the other is polystyrene.
When the potential difference between the plates is 89.0 V , how much electrical energy is stored in the capacitor?
Express your answer with the appropriate units.
