## Homework Statement

The U tube contains the liquid.The length of the liquid in U tube is L. If U tube has an acceleration a in X-axis and we make liquid a small oscillation.Find the period of oscillation.

## The Attempt at a Solution

I know the answer is 2[tex]\pi[/tex][tex]\sqrt{\frac{L}{2\sqrt{g

^{2}+a

^{2}}}}[/tex] but I don't know how to prove it.So,please help me.
