Each shot of the laser gun most favored by Rosa the Closer, the intrepid vigilante of the lawless 22nd century, is powered by the discharge of a 1.15 F capacitor charged to 78.1 kV. Rosa rightly reckons that she can enhance the effect of each laser pulse by increasing the electric potential energy of the charged capacitor. She could do this by replacing the capacitor's filling, whose dielectric constant is 405, with one possessing a dielectric constant of 941. Find the electric potential energy U₁ of the original capacitor when it is charged. Calculate the electric potential energy U₂ of the upgraded capacitor when it is charged. U₁ = U₂ = J
