Question

A lift of mass 1000 kg is going up. The variation is the speed of lift is shown in figure. Then the minimum tension in the rope will be $(g=10m/s^2)$

• A. Zero
• B. 10000 N
• C. 12000 N
• D. 8000 N

Answer 1

The correct option is C 12000 N

$\begin{array}{c}T=m\left(g+a\right)\\ =1000\left(10+2\right)\\ =1000\times 12=12000N\end{array}$

Hence,

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