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

Options

A. ` 9 . 1 xx 10 ^(3)`
B. ` 3 . 0 xx 10 ^(3)`
C. ` 1.1 xx 10^(3)`
D. `0.3 xx 10^(3)`

Answer

C

Explanation

`omega = (1)/(sqrt(LC)) = (1)/( sqrt(30 xx 10^(-6) xx 27 xx 10^(-3)))`
`= 1.1 xx 10^(3) ` rad/sec
