Two small particles of equal masses stant moving in opposite direction from a point `A` in a burtizonetal circule orbic their tangention velocity are `V` and `2V` , respectively as shown in the figure between collsions , the particals move with constant speed After making how many elastic collition , other the then that at `A` these two partical will again reach the point `A` ?

Answer

C

Explanation

Particle with velocity 'v' covers and angle of `120^(@)` and after collision its velocity become '2v'.
It will cover angle of `240^(@)`
