When an object executes S.H.M, its morning acceleration is given by a_{\text {max }}=\omega^2 \mathrm{~A}

Where \omega=\frac{2 \pi}{T}

Therefore, \mathrm{a}_{\max }=\frac{4 \pi^2 \mathrm{~A}}{\mathrm{~T}^2}

\begin{aligned} & F_{\max }=\operatorname{ma}_{\max }=5 \times \frac{4 \times 3.14 \times 3.14}{3.14 \times 3.14} \times(1) \\ & =20 \mathrm{~N} \end{aligned}
