A lift of mass 1000 kg1000 \mathrm{~kg} which is moving with an acceleration of 1 ms−21 \mathrm{~ms}^{-2} in the upward direction, then the tension developed in the string which is connected to lift is:

Options

  1. A9800 N
  2. B10,800 N
  3. C11000 N
  4. D10,000 N

Correct answer

B. 10,800 N

Step-by-step solution

Using the equation T=m(g+a)=1000(9.8+1)=10800 N\begin{aligned} & T=m(g+a)=1000(9.8+1) \\ & =10800 \mathrm{~N} \end{aligned}
