NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyTwo identical cylindrical vessels are kept on the ground and each contain the same liquid of density \(d\). The area of the base of both vessels is \(S\) but the height of liquid in one vessel is \(x_1\) and in the other, \(x_2\). when both cylinders are connected through a pipe of negligible volume very close to the bottom, the liquid flows one vessel to the other until it comes to equilibrium at a new height. The change in energy of the system in the process is:
1. \( \frac{3}{4} g d S\left(x_2-x_1\right)^2 \)
2. \( \frac{1}{4} g d S\left(x_2-x_1\right)^2 \)
3. \(g d S\left(x_2^2-x_1^2\right) \)
4. \( g d S\left(x_2-x_1\right)^2\)
