Two small particles of equal masses start moving in opposite directions from a point \( A \) in a horizontal circular orbit. Their tangential velocities are \( v \) and \( 2 v \), respectively, as shown in the figure. Between collisions, the particles move with constant speeds. After making how many elastic collisions, other than that at \( A \), these two particles will again reach the point \( A \)
