An isolated charged soap bubble of radius Ro = 5.25 cm has a potential of Vo = 231.0 V at its surface. If the bubble shrinks to a radius that is 27.0% of the initial radius, by how much AU does its electrostatic potential energy change? AU = Assume that the charge on the bubble is spread evenly over the surface, and that the total charge on the bubble remains constant. Use k = 8.99 x 10° N-m²/C² for the Coulomb force constant. J
