Mechanical Properties of Fluids

142705 A tube of length $L$ is filled completely with an incompressible liquid of mass $M$ and closed at both ends. The tube is then rotated in horizontal plane about one of its ends with uniform angular velocity $\omega$. The force exerted by the liquid at the other end is

1 $\mathrm{ML} \omega^{2}$
2 $\frac{3 \mathrm{ML} \omega^{2}}{4}$
3 $\frac{\mathrm{ML} \omega^{2}}{2}$
4 $\frac{\mathrm{ML} \omega^{2}}{4}$

1 $\mathrm{Vg}$
2 $10 \mathrm{Vg}$
3 $100 \mathrm{Vg}$
4 $0.1 \mathrm{Vg}$
Where $g$ in $\mathrm{m} / \mathrm{s}^{2}$

142707 Three liquids of equal masses are taken in three identical cubical vessels $A, B$ and $C$. Their densities are $\rho_{A}, \rho_{B}$ and $\rho_{C}$ respectively but $\rho_{A} \lt \rho_{B} \lt \rho_{C}$. The force exerted by the liquid on the base of the cubical vessel is :

1 maximum in vessel $\mathrm{C}$
2 minimum in vessel $\mathrm{C}$
3 the same in all the vessels
4 maximum in vessel $\mathrm{A}$

1 $1: 2$
2 $4: 1$
3 $1: 16$
