AIPMT 2006

MCQ (Single Correct Answer)

-1

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

$${{M{L^2}{\omega ^2}} \over 2}$$

$${{ML{\omega ^2}} \over 2}$$

$${{M{L^2}\omega } \over 2}$$

$$ML{\omega ^2}$$
