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. `1.1s^(-1)`
B. `1.1xx10^(3)s^(-1)`
C. `1s^(-1)`
D. `1xx10^(-3)s^(-1)`

Answer

B

Explanation

Angular frequency of free oscillations of the circuit i.e.
`omega=(1)/(sqrt(LC))=(1)/(sqrt((27xx10^(-3))(30xx10^(-6))s^(-1)))`
`=(10^(4))/(9)s^(-1)=1.1xx10^(3)s^(-1)`
