(B) Given radii of pistons are $r_1 = 2 \ m$ and $r_2 = 5 \ m$. Let $m_1$ be the mass placed on piston $P_1$ and $m_2 = x$ be the mass placed on piston $P_2$.According to Pascal's law,the pressure at the same horizontal level in a continuous static fluid is the same.$p_1 = p_2$$\frac{F_1}{A_1} = \frac{F_2}{A_2}$Since $F = mg$ and $A = \pi r^2$,we have:$\frac{m_1 g}{\pi r_1^2} = \frac{m_2 g}{\pi r_2^2}$$\frac{m_1}{r_1^2} = \frac{m_2}{r_2^2}$Substituting the given values:$\frac{m_1}{2^2} = \frac{x}{5^2}$$\frac{m_1}{4} = \frac{x}{25}$$m_1 = \frac{4}{25} x = 0.16 x$Thus,the minimum mass that should be kept on $P_1$ is $0.16 x$.

$A$ hydraulic lift is shown in the figure. The radii of the movable pistons $P_1$ and $P_2$ are $2 \ m$ and $5 \ m$ respectively. If a block of mass $x$ is placed on $P_2$,then the minimum mass that should be kept on $P_1$ to lift the block on $P_2$ is (in $x$)

Why does the bottom of a bottle filled with liquid break when the cork is hit?

In a hydraulic lift,compressed air exerts a force $F$ on a small piston of radius $3 \ cm$. Due to this pressure,the second piston of radius $5 \ cm$ lifts a load of $1875 \ kg$. The value of $F$ is (Acceleration due to gravity $= 10 \ m \ s^{-2}$) (in $N$)
