A 12.5 μF capacitor is connected to a power supply that keeps a constant potential difference of 24.0 V across the plates. A piece of material having a dielectric constant of 3.75 is placed between the plates, filling the space. How much energy is stored in the capacitor before the material was inserted (in mJ)?
