A cylindrical vessel containing a liquid is rotated about its axis so that the liquid rises at its sides as shown in the figure . The radius of vessel is 5 cm and the angular speed of rotation is ` omega` rad `s^(-1)`. The difference in the height , h ( in cm ) of liquid at the centre of vessel and at the side will be :

A

`(25 omega^(2))/(2g)`

B

`(2 omega^(2))/(25g)`

C
