Question

To paint the side of a building, painter normally hoists himself up by pulling on the rope A as in figure. The painter and platform together weigh 200N. The rope B can withstand 300N. Then

  1. The maximum acceleration that painter can have upwards is 5m/s2 .    
  2. To hoist himself up, rope B must withstand minimum 400N force.    
  3. Rope A will have a tension of 100 N when the painter is at rest.    
  4. The painter must exert a force of 200N on the rope A to go downwards slowly.    

The correct answer is: Rope A will have a tension of 100 N when the painter is at rest.
