83. (a) At any time, the total energy Uin the circuit is the sum of the energy UEin the capacitor and the energy UBin the inductor. When UE= 0.500UB(at time t), then UB= 2.00UEand U = UE+ UB= 3.00UE. Now, UEis given byqC22/, where qis the charge on the capacitor at time t. The total energy Uis given by QC22/, where Qis the maximum charge on the capacitor. Thus, 223.000.577.3.00QqQqQCC=⇒=
