Question

Six particles situated at the corners of a regular hexagon of side a move at a constant speed v. Each particle maintains a direction towards the particle at the next corner. Calculate the time the particles will take to meet each other.
A. `2d//3v`
B. `2d//v`
C. `3d//2v`
D. `4d//3v`

Answer 1

Correct Answer - B

`(v_(A//B))_(x)=v-v cos 60^(@)=v/2`
`t=d/(v//2)=(2d)/v`
