A person of mass `60kg` is inside a lift of mass `940kg` and presses the button on control panel. The lift starts moving upword with an acceleration `1.0m//s^(2)` . If `g=10m//s^(2)` , the tension in the supporting cable is.

`9680N`

`11000N`

`1200N`

`8600N`

Text Solution

Verified by Experts

The correct Answer is:

Total mass=Mass of lift+Mass of person
`=940+60=1000kg`
`T-mg=ma`
Hence, `T-1000xx10=1000xx1`
`T=11000N` .
