A monkey of mass 40 kg climbs a rope. Which can withstand a maximum tension of 600 N. In which of the following cases will the rope break: The monkey
falls down the rope nearly under gravity
[ ignor the mass of the rope. Take g = 10 m`cdot s^(-2)`]

Explanation

Real weight of the monkey = 40 kg.wt = 40`xx`10 N = 400 N, so the rope can withstand his real weight. Here g = 10 m`cdot s^(-2)` = actual acceleration due to gravity, acting downwards.
When the monkey falls freely under gravity, then a = g
thus relative downward acceleration,
Hence, apparent weight = mg. = 0
In this case, the rope does not break.
