LC Circuits: A series circuit contains an 80-?F capacitor, a 0.020-H inductor, and a switch. The resistance of the circuit is negligible. Initially, the switch is open, the capacitor voltage is 50 V, and the current in the inductor is zero. At time t = 0 s, the switch is closed. How long after closing the switch does the magnetic energy in the inductor first reach its maximum value?

A. 2.0 ms B. 4.0 ms C. 6.0 ms D. 8.0 ms E. 10 ms
