The switch in Figure P7-40 has been open for a long time and is closed at \(t=0\). The circuit parameters are \(L=2 \mathrm{H}, C\) \(=0.5 \mu \mathrm{F}, R=250 \Omega\), and \(v_{\mathrm{F}}(\mathrm{O})=5 \mathrm{~V}\).

(a) Find \(v_{\mathrm{C}}(t)\) and \(i_{\mathrm{L}}(t)\) for \(t \geq 0\).
(b) Is the circuit overdamped, critically damped, or underdamped?
(c) Use Multisim to simulate your results.
