A `50 kg` person stand on a `25 kg` platform. He pulls on the rope which is connected to the rope which is attached to the platform `via` the frictionless pulley as shown in the figure. The platform moves upwards at a steady rate if the force with which the person pulls the rope is

500N

250 N

25 N

None of these

Text Solution

Verified by Experts

The correct Answer is:

Steady rate means, net force = 0 `:. 3T = 75g = 750` or T = 250N
