Question

The mass of a lift $600kg$ and it is moving upward with a uniform acceleration of $2m/s^2$.Then the tension in the cable of the lift is-

• A. 7200 N
• B. 5880 N
• C. 4680 N
• D. Zero N

Answer 1

The correct option is A 7200 N

Since the lift its moving upwards$,$

the equation will be$,$

$ma=T-mg$

$T=ma+mg$

$T=m(a+g)$

$T=600(2+10)$

$T=600\times 12$

$T=7200N$

Hence,

option $\left(A\right)$ is correct answer.
