Vedclass · Answer

(B) Let the height difference between the two liquid levels be $h$. According to the principle of hydrostatics,the pressure at the same horizontal level in a continuous static fluid is the same. Considering the horizontal level at the lower liquid surface,the pressure on the left side is $P + \rho g h$,where $\rho$ is the density of the liquid and $g$ is the acceleration due to gravity. The pressure on the right side is $p$. Equating the two,we get $P + \rho g h = p$. Since $\rho, g, h > 0$,it follows that $P + \rho g h > P$. Therefore,$p > P$,which means $P < p$.
