## Homework Statement

A liquid is placed in a U-Shaped tube. Initially both are at the same level. Total length of liquid is L. But later one side is displaced from equilibrium by X.(Difference of both sides is 2x now). Show that the water will oscillate harmonically in the form of a=-w squared x. Hence derive an expression for period of oscillation in terms of L.
