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