Question

A machine, in an amusement park, consists of a cage of the end of one arm, hinged at O. The cage revolves along a vertical circle of radius r (ABCDEFGH) about its hinge O, at constant linear speed v= square root of g r end root . The cage is so attached that the man of weight 'W' standing on a weighing machine, inside the cage, is always vertical. Then which of the following is correct

  1. The weight reading at A is greater than the weight reading at E by 2W    
  2. The weight reading at G = W    
  3. The ratio of the weight reading at E to that at A = 0    
  4. The ratio of the weight reading at A to that at C = 2    

The correct answer is: The weight reading at G = W
