A long cylinderical 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 5 cm and its rotational speed is 2 rotatins per second, then the difference in the heights between the centre and the sides, in cm. will be :
