Oscillation of the liquid

Score: 3 Points

Suppose, a U-tube is filled with liquid and the level of the liquid is in equilibrium at both side. If a small push is given at the one side of the U-tube, each side of the level of the liquid will start to oscillate.
What is the frequency of this oscillation?
$g=10\frac{m}{s^2}$
$L=5m$, the length of the liquid.
