The correct answer is:
$0.2 \pi \mathrm{s}$
$$
\begin{aligned}
& \mathrm{k}=400 \mathrm{~N} / \mathrm{m} \\
& \mathrm{m}=0.04
\end{aligned}
$$
From the graph,
$$
\mathrm{K}=\frac{\mathrm{F}}{\mathrm{x}}=\frac{8}{2}=4
$$
From $T=2 \pi \sqrt{\frac{M}{K}}$,
we get
$$
\mathrm{T}=2 \pi \sqrt{\frac{0.04}{4}}=0.2 \pi \mathrm{s}
$$
