83. (a) At any time, the total energy U in the circuit is the sum of the energy U E in the capacitor and the energy U B in the inductor. When U E = 0.500 U B (at time t ), then U B = 2.00 U E and U = U E + U B = 3.00 U E . Now, U E is given by qC 2 2 / , where q is the charge on the capacitor at time t . The total energy U is given by QC 2 2 / , where Q is the maximum charge on the capacitor. Thus, 22 3.00 0.577 . 3.00 Qq Q qQ CC =⇒ =
