A lift of mass $1000 \mathrm{~kg}$ which is moving with an acceleration of $1 \mathrm{~ms}^{-2}$ in the upward direction, then the tension developed in the string which is connected to lift is:
9800 N
10,800 N
11000 N
10,000 N
Solution
Using the equation
$\begin{aligned}
& T=m(g+a)=1000(9.8+1) \\
& =10800 \mathrm{~N}
\end{aligned}$
