JEE MAIN - Physics (2022 - 26th July Morning Shift - No. 16)
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 $$\left(g=10 \mathrm{~m} / \mathrm{s}^{2}\right)$$.
$$T=700 \mathrm{~N}$$ while climbing upward
$$T=350 \mathrm{~N}$$ while going downward
Rope will break while climbing upward
Rope will break while going downward
Explanation
Tdown = 50 $$\times$$ (10 $$-$$ 4)
= 50 $$\times$$ 6
= 300 N
Tup = 50 $$\times$$ (10 + 5)
= 50 $$\times$$ 15
= 750 N
$$\Rightarrow$$ Rope will break while climbing up.
