Expert Answer:

The two particles are initially moving horizontally in opposite directions.
 
Let v1x = -1 m/s along -x-axis, and v2x = 1 m/s along +x-axis.
 
Their initial velocities in the y-direction is zero.
 
Let us say that after time 't' their velocity vectors become mutually perpendicular to each other.
