Polystyrene has dielectric constant 2.6 and dielectric strength 2.0 × 10^7 v/m. a piece of polystyrene is used as a dielectric in a parallel-plate capacitor, filling the volume between the plates.
(a) when the electric field between the plates is 78 % of the dielectric strength, what is the energy density of the stored energy?
(b) when the capacitor is connected to a battery with voltage 500.0 v, the electric field between the plates is 78 %of the dielectric strength. what is the area of each plate if the capacitor stores 0.20 mj of energy under these conditions?
