A tube of length \[L\] is filled completely with an incompressible liquid of mass \[M\]and closed at both the ends. The tube is then rotated in horizontal plane about one of its ends with a uniform angular velocity \[\omega \]. The force exerted by the liquid at the other end is

• A. \[\frac{ML{{\omega }^{2}}}{2}\]        
• B. \[ML{{\omega }^{2}}\]
• C. \[\frac{ML{{\omega }^{2}}}{4}\]        
• D. \[\frac{M{{L}^{2}}{{\omega }^{2}}}{2}\]
