A man is raising himself and the crate on which he stands with an acceleration of `5ms^(-2)` by a massless rope-and-pulley arrangement. Mass of the man is 100kg and that of the crate is 50 kg. If `g=10ms^(-2)`, then the tension in the rope is

A

`2250N`

B

`1125N`

C

`750N`

D

`375N`

Text Solution

Verified by Experts

The correct Answer is:
B
`M_(1)=100kg` , `m^(2)=50kg` , `a=5m//s^(2)`
`T+N-m_(1)g=m_(1)a`
`T-N=mg=m_(2)a`
Solving these: `T=1125N` and
`N375N` .
