Is the answer 3v?
Use T.v=0 actually diagram is not clear there.
how to use that ?
Bro why here component of velocity along direction of string is not same?
That will complicate it as other end of string is joined to upper wall you cannot link velocity of horizontal part only .
net velocity along string is same see
Now got it thanks @Siddhant_Mudholkar
Try 4th one. Different methods are welcome but there's one method which blew my mind.
There's one long method I know- taking integral of half discs ...
Using projection area? Did same in electrostatics
We’re on the same line. Think further. A mind blowing method incoming.
Sorry idk what that is @Siddhant_Mudholkar
Check krotov it's there best method to tackle this problem @seshu_ram
Sorry I don’t have krotov. Can you please send a picture?

Please share the question number @Siddhant_Mudholkar
3.3 in electricity and magnetism section
Thanks went through the solution. But I feel that this too is a bit over complex. I didn’t understand well coz chapter isn’t there.
Not complex. Wait your teacher will tell that method In 12th it's heck easy if u understand it
