Consider three particles which are situated at the vertices of equilateral triangle of side .Each of the particles move with constant speed . always has its velocity along , always has its velocity along , always has its velocity along . At what time in seconds will the particles meet each other?
If you think that they will never meet , prove it and enter the answer as 1.1.
If you think that they will meet at infinity , prove it and enter the answer as 2.2.
