A monkey of mass $50 \mathrm{~kg}$ climbs on a rope which can withstand the tension (T) of $350 \mathrm{~N}$. If monkey initially climbs down with an acceleration of $4 \mathrm{~m} / \mathrm{s}^{2}$ and then climbs up with an acceleration of $5 \mathrm{~m} / \mathrm{s}^{2}$. Choose the correct option $\left(g=10 \mathrm{~m} / \mathrm{s}^{2}\right)$.
