Question

For the LC circuit, whose graph of charge $\left(q\right)$ on capacitor versus time $\left(t\right)$ is shown in the figure. The frequency of oscillations of charge is -

• A. $0.425\text{Hz}$
• B. $0.325\text{Hz}$
• C. $0.225\text{Hz}$
• D. $0.125\text{Hz}$

Answer 1

The correct option is D $0.125\text{Hz}$


From the figure, the time period of oscillations of charge is,

$T=8\text{s}$

So, frequency,

$f=\frac{1}{T}=\frac{1}{8}=0.125\text{Hz}$

Hence, option $\left(D\right)$ is the correct answer.
