A person of mass 60 kg is inside a lift of mass 940 kg and presses the button on control panel. The lift starts moving upwards with an acceleration 1.0 ~m / s ^2 . If g =10 ~ms ⁻² , the tension in the supporting cable is

Options

  1. A8600 N
  2. B9680 N
  3. C11000 N
  4. D1200 N

Correct answer

C. 11000 N

Step-by-step solution

Total mass =(60+940) kg =1000 ~kg Let T be the tension in the supporting cable, then T-1000 g=1000 1 T =1000 11=11000 ~N
