Problem

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 a 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{M\omega^2 L}{2}

M\omega^2 L

\frac{M\omega^2 L}{4}

\frac{M\omega^2 L^2}{2}
