Answer:
d. (2a)/v
Explanation:
Let us concentrate on two particles say A and B only.
Initial separation between two particles = side of the hexagon=a
Final separation =0
Thus, relative displacement between two particles =a.
Particle B has a component of velocity v cos 60& along AB
Thus, relative velocity with which A approaches B is v-vcos 60=v/2
As v is uniform& time taken by theese two particles to meet = relative displacement/relative velocity =a/(v/2)=2a/v
Hence the time taken by particles to meet each other =2a/v
