A monkey of mass 40 kg climbs on a rope which can withstand a maximum tesion of 600 N In which of the following cases will the rope break ? The monkey
(a) climbs up with an acceleration of `6 ms^(-2)`
(b) climbs down with an acceleration of `4 ms^(-2)`
(c) climbs up with a unifrom speed of `5 ms^(-1)` (d) falls down the rope nearly freely under gravity Ignore the mass of the rope .

Explanation

(a) `T-40g=240 rArr T=632N`
(b) `392-T=160 rArr=232N`
(c) T=392N
The rope will break in case (a) as `Tg600N`.
