143163 A water tank is in the shape of a cube with walls of $4 \mathrm{~m}$. When the tank is half-filled with water, the water exerts a force $F$ on the walls. What force does the water exert on the walls when the tank is completely filled?

143164 A hydraulic lift is shown in the figure. The radii of the movable pistons $P_{1}$ and $P_{2}$ are of $2 \mathrm{~m} \& 8 \mathrm{~m}$ respectively. If a body of mass $2 \mathrm{~kg}$ is placed on piston $P_{1}$ then the force on piston $P_{2}$ is-
(Ignore atmospheric pressure, acceleration due to gravity $=10 \mathrm{~ms}^{-2}$ )

143165 A hydraulic lift is shown in the figure. The movable piston $A B$ and $C$ are of radius $10 \mathrm{~cm}$, $100 \mathrm{~cm}$ and $5 \mathrm{~m}$ respectively. If a body of mass $2 \mathrm{~kg}$ is placed on piston $A$, the maximum masses that can be lifted by piston $B$ and $C$ are respectively

143166 A container is filled to a height of $20 \mathrm{~cm}$ with water. A $30 \mathrm{~cm}$ thick layer of oil with specific gravity 0.8 floats on the top of water. If the density of water is $1000 \mathrm{kgm}^{-3}$ and atmospheric pressure is $1 \times 10^{5} \mathrm{~Pa}$, then the total pressure at the bottom of the container is
