Each shot of the laser gun favored by rosa the closer, the intrepid vigilante of the lawless 22nd century, is powered by the discharge of a 1.81-f capactor charged to 73.9 kv. rosa rightly reckons that she can enhance the effect of each laser pulse by increasing the electric potential energy of the charged capacitor. this she would do by replacing the capacitor's filling, whose dielectric constant is 435, with one possessing a dielectric constant of 943.find the electric potential energy of the original capacitor when it is charged. (in joules)calculate the electric potential energy of the upgraded capacitor when it is charged. ( in joules)
