# SHM of liquid

**Classical Mechanics**Level 4

A V-shaped tube attached to the ground with its vertex. It's one leg makes an angle of \( 30 ^\circ\), and the other leg makes an angle of \(60 ^\circ\) with the horizontal. The tube is filled with a liquid in a total length of \(1\text{ m}\). Now the liquid at one side is displaced a little.Find the Time - period of SHM.

Your answer can be represented as \[\sqrt{\dfrac{a \pi^b}{c (\sqrt{d} + 1)}} \; , \]

where \(a,b,c\) and \(d\) are positive integers with \(a,c\) coprime and \(d\) square-freee.

Enter your answer as \( a + b + c + d \).

**Details and Assumptions**:

Neglect surface tension , viscuous force and friction.

\( g = 10\text{ m/s}^2\).
