I need explanations on LC circuit.

Consider the following LC circuit. The capacitor is initially charged, with +Q0 on the

upper plate. At t=0, the switch is closed.

(a) Apply Kirchhoff's loop rule to the circuit and write down a differential equation for the

charge on the upper plate of the capacitor, Q(t).

(b) Sketch a graph of the current in the circuit as a function of time.

(c) How does the energy in the system change over time?
