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 $\displaystyle 5$ cm and the angular speed of rotation is $\displaystyle \omega \mathrm{rad} \mathrm{s}^{-1}$. The difference in the height, $\displaystyle h$ (in cm ) of liquid at the centre of vessel and at the side will be :
Official answer
(2)
$\displaystyle \frac{25 \omega^2}{2 \mathrm{~g}}$
