Answer 1

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
