Two 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 x1 and in the other, x2 . When both cylinders are connected through a pipe of negligible volume very close to the bottom, the liquid flows from 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:
A
gdS(x2 + x1)2
B
gdS$$\left( {x_2^2 + x_1^2} \right)$$
C
$${1 \over 4}gdS{\left( {{x_2} - {x_1}} \right)^2}$$
D
$${3 \over 4}gdS{\left( {{x_2} - {x_1}} \right)^2}$$
