@manan_uppadhyay try this. Not getting.

Tried using bernoulli and continuity equations, not getting it.

Same.

Can you try poiseuille’s law?
I am making some error. You might get it.

Convert it to current electricity problem,
Pressure~Voltage
Find the resistances in terms of l and r givrn, and then use KVL.

Can you write it

This is the concept behind this question…

Guys I thing there is error becoz given answer is (2,4) but i did it (1,4) but when i trasspassed it in google then the figure is wrong. and also it is question of DRILL ADV ALLEN So, are these type of errors rare or often

Option 1 is wrong becoz point B is in the liquid…and pressure will be less than P⁰ . (concept of excess presaure)

Ok Bro agreed. But Radius of meniscus must be 2S/rho g h
