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 . If g = 10 , the tension in the supporting cable is
Total mass = Mass of lift + Mass of person
=940+ 60= 1000kg
T- mg= ma
Hence, Z- 1000 x l0 =1000 x I
T = 11000N
