The mass of lift is 1000 kg. The tension in the cable of the lift while the lift is moving upward with the acceleration of 2 ms-2 is:
20000 N
11000 N
9800 N
11800 N
T = m (g + a) = 1000 (9.8 + 2) = 11800 N
A lift of mass 1000kg , which is moving with an acceleration of 1 m/s2 in upward direction has tension developed in its string equal to:
