2. Consider the following capacitors under voltage constant condition. (a) Plot E, V through the capacitor, one with a dielectric slab and the other with a metal slab. The rest of the space is filled with vacuum. Let V = 0 be defined at the right capacitor plate. Pay special attention to making sure the different regions on the plots line up with the schematic. (b) Which capacitor has the higher maximum E value? Justify your answer. (c) Which capacitor stores more total internal energy? Justify your answer.
