In LC oscillation resistance is 100 `Omega` and inductance and capacitance is 1 H and `10 mu F` . Find the half power of frequency .

A

266.2

B

366.2

C

166.2

D

233.2

Text Solution

Verified by Experts

The correct Answer is:
A
`f_(n)=omega_(0)-(R )/(2L)=(1)/(sqrt(LC))-(R )/(2L)`
`=(1)/(sqrt(1xx10xx10^(-6)))-(100)/(2xx1)`
`=(1000)/(sqrt(10))-(100)/(2)`
`=100 [sqrt(10)-0.5]=266.27`
