Question

In a LC circuit angular frequency at resonance is ω. What will be the new angular frequency when inductor's inductance is made 2 times and capacitance is made 4 times?

• A. $\frac {ω}{\sqrt 2}$
• B. $\frac {ω}{2\sqrt 2}$
• C. $2ω$
• D. $\frac {2ω}{\sqrt 2}$

Answer 1

Answer: (B)

$\frac {ω}{2\sqrt 2}$

Answer 2

The correct option is (B): $\frac {ω}{2\sqrt 2}$.
