$T=8 \,s$
$ \omega=\frac{2 \pi}{8}=\frac{\pi}{4}$
$x_1=A \sin \frac{\pi}{4}=\frac{A}{\sqrt{2}}$
$x_2=A \sin \frac{\pi}{4} \times 2-A \sin \frac{\pi}{4}=A-\frac{A}{\sqrt{2}}=\frac{A}{\sqrt{2}}(\sqrt{2}-1)$
$\frac{x_1}{x_2}=\frac{1}{\sqrt{2}-1} \times \frac{\sqrt{2}+1}{\sqrt{2}+1}=\sqrt{2}+1$


If a student plots graphs of the square of maximum charge $( Q_{Max} ^2 )$ on the capacitor with time$(t)$ for two different values $L_1$ and $L_2 (L_1 > L_2)$ of $L$ then which of the following represents this graph correctly? (plots are schematic and not drawn to scale)
