A long cylindrical vessel is half filled with a liquid. When the vessel is rotated about its own vertical axis, the liquid rises up near the wall. If the radius of vessel is $\displaystyle 5$ cm and its rotational speed is $\displaystyle 2$ rotations per second, then the difference in the heights between the centre and the sides, in cm, will be:
