An isolated charged soap bubble of radius Ro = 4.65 cm is at a potential of V = 283.0 volts. If the bubble shrinks to a ridios that is 39.0% of the initial radius, by how much does its electrostatic potential encergy U change? Assume that the charge on the bubble is spread evenly over the surface, and that the total charge on the bubble remains constant. AU = U Utal = TOOLS
