The mass of a lift is 2000 kg. When the tension in the supporting cable is 28000 N, then its acceleration is
Text Solution
Verified by ExpertsThe correct answer is:
B
Apparent weight > actual weight, then the lift is accelerating upward. Here, lt is accelerating upward at the rate of a Hence, equation of motion is written as
R – mg = ma
28000 – 20000 = 2000 a
a = 
= 4ms -2 upwards
