The mass of a lift is `2000kg` . When the tensioon in the supporting cable is `28000N` , then its acceleration is.

A

`14 ms^(-2)` upwards

B

`30 ms^(-2)` downwards

C

`4 ms^(-2)` upwards

D

`4 ms^(-2)` downwards

Text Solution

Verified by Experts

The correct Answer is:
C
`sumF=ma`
`implies T-mg=ma `
`a=(T-mg)/(m)=4m//s^(2)`
