A dielectric-filled parallel-plate capacitor has plate area A=10.0 cm2, plate separation d=6.00 mm and dielectric constant k=5.00. The capacitor is connected to a battery that creates a constant voltage V=12.5 V. Throughout the problem, use E0=8.85*10^-12 C2/N*m2

Part B The dielectric plate is now slowly pulled out of the capacitor, which remains connected to the battery. Find the energy U of the capacitor at the moment when the capacitor is half-filled with the dielectric. Express your answer numerically in joules. > View Available Hint(s) AEd U2 = Submit
