Two bodies of masses m and my have equal kinetic energies what is the ratio of their linear momenta

26.

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 ω. The force exerted by the liquid at the other end is

A.

Let the length of a small element of tube be dx. Mass of this element
