(A) Three particle system: differently colored vertices of the triangles represent the positions of the particles at different instants of time. The positions of particle 1 at various times are labeled as 1, 2,...., 7. (B) Expanded view of the trajectory of particle 1 which executes a zigzag motion along the perpendicular bisector to the line between particles 2 and 3 as it comes within Δx from the bisector (see positions 5, 6, 7 of particle 1).
