# Q7.7  A charged $30\mu F$ capacitor is connected to a $27mH$  inductor. What is the angular frequency of free oscillations of the circuit?

Given

Capacitance  $C=30\mu F=30*10^{-6}$

Inductance $L = 27mH = 27*10^{-3}H$

Now,

Angular Frequency

$\omega _r=\frac{1}{\sqrt{LC}}=\frac{1}{\sqrt{30*10^{-6}*27*10^{-3}}}=1.11*10^{3}rad/sec$

Hence Angular Frequency is $1.11*10^{3}rad/sec$
