Question

Three point particles P, Q, R move in circle of radius ‘r’ with different but constant speeds. They start moving at t = 0 from their initial positions as shown in the figure. The angular velocities (in rad/ sec) of P, Q and R are 5p, 2p & 3p respectively, in the same sense. The time interval after which they are at same angular position

  1. 2 over 3 sec    
  2. 1 over 6 sec    
  3. 1 half sec    
  4. 3 over 2 sec    

The correct answer is: 3 over 2 sec
