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

Options

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

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")`
