  1. H,2H    
  2. H/2    
  3. H,4H    
  4. H/4, H    

The correct answer is: H/2

A smooth narrow tube in form of an arc AB of a circle of centre ' O ' and radius ' R ' is fixed so that A is vertically above ' O ' and OB is horizontal. Particles P of mass ' m ' and Q of mass ' 2 m ' with a light inextensible string of length fraction numerator pi r over denominator 2 end fraction connecting them are placed in side the tube with P at A and Q at B and released from rest. Assuming the string remains taut during motion, find the speed of particles when P reaches B ?
