Q: 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

(a) 1200 N

(b) 8600 N

(c) 9680 N

(d) 11000 N

Ans: (d)
Sol: T = m(g+a)

T = 1000(10+1)

T= 11000 N
