Apparent Weight & Lift

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/s2. If g = 10 ms ${}^{-2}$ , the tension in the supporting cable is

Show answer and solution

Answer: (c)

Total mass $= 60 + 940 = 1000$ kg.
$T = m(g + a) = 1000 \times (10 + 1) = 11000$ N
So the answer is (c) 11000 N.
