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`, respectively. As shown in the figure. Between collisions, the particles moves with constant speeds. After making how many elastic collisions, other than that at `A`. these two particles will again reach the point `A`?
