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
Options
(a) 8600 N
(b) 9680 N
(c) 11000 N
(d) 1200 N
Correct Answer:
11000 N
Explanation:
Total Mass = (60 + 940) kg = 1000 kg
Let T be the tension in the supporting cable, then,
T =M (g+a)
⇒ T = 1000(10+1) =11000 N
