Text Solution

Verified by Experts
The correct answer is:
A

: Here mass of monkey m = 40kg

Maximum tension the rope can stand T = 500N

Tension in the rope will be equal to apparent weight of the monkey (R)

The rope will break when R exceeds T

When the monkey climbs up with an acceleration

R>T

Hence the roe will break

When the monkey climbs down with an acceleration

R<T

Hence the rope will not break

When the monkey climbs up with a uniform speed

its acceleration a=0

R<T

Hence the rope will not break

When the monkey falls down the rope freely under gravity

Hence the rope will not break
