An ideal LC circuit consists of an inductor of inductance L and a capacitor of capacitance C.

Initially, the capacitor holds a maximum charge Q_max and the current in the circuit is zero.

The circuit oscillates freely, and at a subsequent instant during the first quarter-cycle, the charge on the capacitor is q = (1/2)Q_max.

Which of the following correctly ranks the fractional electric energy U_E / U_tot, the fractional magnetic energy U_B / U_tot, the fractional current I / I_max, and the fractional rate of energy transfer P / P_max at this instant, where P = |dU_E / dt| and P_max is the maximum possible rate of energy transfer in the circuit?
