A monkey of mass `40kg` climbs on a massless rope of breaking strenght `600N`. The rope will break if the monkey (Take `g =10 m//s^(2)`) .

Options

A. climbs up with a uniform speed of `6m//s`
B. climbs up with an acceleration of `6m//s^(2)`
C. climbs with an acceleration of `4m//s^(2)`
D. climbs down with a uniform speed of of `5m//s^(2)`

Answer

B

Explanation

To move up with an acceleration a the monkey will push the rope downwards with a force of ma.
`T_(max) = mg + ma_(max)` .
