Question

A monkey of mass 50 kg climbs on a rope which can withstand the tension (T) of 350 N. If monkey initially climbs down with an acceleration of 4 m/s2 and then climbs up with an acceleration of 5 m/s2. Choose the correct option (g = 10 m/s2).

• A. T = 700 N while climbing upward
• B. T = 350 N while going downward
• C. Rope will break while climbing upward
• D. Rope will break while going downward

Answer 1

Answer: (C)

Rope will break while climbing upward

Answer 2

$T_{down} = 50 × (10 ^{– 4})$
$T_{down} = 50 × 6$
$T_{down} = 300\ N$
$T_{up} = 50 × (10 + 5)$
$T_{up} = 50 × 15$
$T_{up} = 750\ N$
$⇒$ Rope will break while climbing up.

So, the correct option is (C): Rope will break while climbing upward.
