Homework Help: Question on circular motion

  1. Mar 26, 2012 #1
    1. The problem statement, all variables and given/known data
    Three point particles P , Q , R move in circle of radius r with different but constant speeds . They start moving from their initial position as shown in figure
    The angular velocities (in radian/sec) of P , Q , R are 5∏ , 2∏ , 3∏ respectively in the same sense .
    The time interval after which they are at same angular position.

    3. The attempt at a solution
    Let theta be the angle covered by R in time T
    T*3∏ = theta + n1∏ (i)
    T*2∏ = (∏/2+theta) + n2∏ (ii)
    T*5∏ = (∏+theta) + n3∏ (iii)
