Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.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
