I was able to get separation using dx/dt = -v/2 and then integrating with proper limits Can't figure out accn

Join each point with a line from the center. Then each point has some component of velocity perpendicular to this, which makes it rotate and one which pushes the point towards the center, making the shape smaller. At t=2a/v, find the length of the line joining center and point which will give separation between 2 points using geometry while also giving acceleration by v^2/r ig.

I just can't get this to work Can u please share the working @SirLancelotDuLac some help here too pls ...

Is the answer (a),(b),(c) and (d)?

yep all correct

Ah man, then there seems to be a slight problem. They have only taken coriolis acceleration while disregrading centripetal acceleration of particles.

Ohhh , how did u get the ans then

I only considered the Coriolis component. Otherwise sqrt(7) ka factor was occuring.

This was as far as I solved.

did you try to gpt it?

Did you get the point where we took the components of Velocity? One of the components makes the hexagonal shape made by the points rotate, while the other tries to scale it down. Since coriolis force is given by 2(r'×omega) we put the values of both In this case r'=radial components of Velocity while omega is tangential component/r

Challenging physics problem | 2D motion
Three particles A, B and C are situated at the vertices of an equilateral triangle ABC of side d at time t = 0. Each of the particles moves with constant speed v. A always has its velocity along AB, B along BC and C along CA. At what time will the particles meet each other? This is a famous problem from the 2D kinetmatics (Motion in a plane). T...
