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 ω rad s^{–1}. The difference in the height, h (in cm) of liquid at the centre of vessel and at the side will be

\(A) \frac{2\omega^2}{25g}\)

\(B) \frac{5\omega^2}{2g}\)

\(C)\frac{25\omega^2}{5g}\)

\(D) \frac{2\omega^2}{5g}\)
