A tube of length $\displaystyle 50$ cm is filled completely with an incompressible liquid of mass $\displaystyle 250$ g and closed at both ends. The tube is then rotated in horizontal plane about one of its ends with a uniform angular velocity $\displaystyle x \sqrt{F} \mathrm{rad} \mathrm{s}^{-1}$. If F be the force exerted by the liquid at the other end then the value of $\displaystyle x$ will be \_\_\_\_.
