A certain parallel-plate capacitor is filled with a dielectric for which K = 6.50. The area of each plate is 0.0524 m², and the plates are
separated by 2.97 mm. The capacitor will fail (short out and burn up) if the electric field between the plates exceeds 179 KN/C. What is
the maximum energy that can be stored in the capacitor?
