The correct answer is:
$98.596 \mathrm{~N}$
Maximum acceleration
$\begin{gathered}A_{\max }=a \omega^2=\frac{a \times 4 \pi^2}{T^2}=\frac{1 \times 4 \times(3.14)^2}{0.2 \times 0.2} \\ F_{\max }=m \times A_{\max }=\frac{0.1 \times 4 \times(3.14)^2}{0.2 \times 0.2}=98.596 \mathrm{~N}\end{gathered}$
$\begin{gathered}A_{\max }=a \omega^2=\frac{a \times 4 \pi^2}{T^2}=\frac{1 \times 4 \times(3.14)^2}{0.2 \times 0.2} \\ F_{\max }=m \times A_{\max }=\frac{0.1 \times 4 \times(3.14)^2}{0.2 \times 0.2}=98.596 \mathrm{~N}\end{gathered}$
