Question

You have a solenoid 20cm in diameter and 10cm long containing 505 turns. You also have a 100 mF capacitor and a 40V battery. You use the battery to fully charge the capacitor. Then you connect each end of the capacitor to each end of the solenoid to form an LC circuit. A) What is the charge on the capacitor 2 seconds after the circuit is connected?

A more realistic version of this circuit includes the resistance of the solenoid, and forms an RLC circuit. Assume for part B that the solenoid has a resistance of 0.5 Ohms. B) What is the charge on the capacitor 2 seconds after the circuit is connected?
