This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.

Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

I completely agree. I suggest we now delete our previous comments on the other Note to ensure smooth reading. You could also write in the rules about this Note.

Since the particle at point P is performing circular motion about the center of the arc, essentially we need to find the velocity at point P. This can be found by taking a section/tube of the manometer and then using Bernoulli's Equation.Their might be other approaches too.

@Ishan Dasgupta Samarendra

In your question will tension in the string cause the velocity to decrease ? Or will there even be tension in the string ?

Log in to reply

Actually that is something you are supposed to work out. And why will there not be/be tension in the rope?

No one except Ronak have solved it and Ronak is not participating. So please post the solution and the next question too. Nice Question btw !

Someone give a hint to Surya's problem or @Surya Prakash you give hint here.
