A charged `30 mu F` capacitor is connected to a 27 mH inductor. What is the frequency of free oscilolations of the circuit ?

Explanation

Here, `C = 30 mu F = 30x 10^(-6) F, L = 27 mH = 27 xx 10^(-3) H, v = ?`
`v = (1)/(2 pi sqrt(LC)) = (1 xx 7)/(2 xx 22 sqrt(27 xx 10^(-3) xx 30 xx 10^(-6))) = (7 xx 10^(4))/(44 xx 9) = 1.767 xx 10^(2) cps`
