(a) After the switch is thrown to position b the circuit is an LC circuit. The angular frequency of

oscillation is ω = 1/

√

LC. Consequently,

f =

= 275 Hz .

(b) When the switch is thrown, the capacitor is charged to V = 34.0V and the current is zero. Thus,

the maximum charge on the capacitor is Q = V C = (34.0V)(6.20

current amplitude is
