A person of mass 60 kg is inside a lift ...

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

A

1200 N

B

8600 N

C

9680 N

D

11000 N

Text Solution

Verified by Experts

The correct Answer is:
D
m = 60 kg , Lift mass (M) = 940 kg , `a = 1m//s^(2)`
`(M + m) a = T - (M + m)g `
`rArr T = 11000 N`
