Q. A cylinder is filled with liquid of density $d$ upto a height $h$. If the cylinder is at rest, then the mean pressure of the walls is
A) $hdg/4$
B) $hdg/2$
C) $2\ hdg$
D) $hdg$
Explanation
(b) Pressure at the bottom $= hdg$
Pressure at the top due to liquid column =0
$\therefore\ \ \ Mean\ pressure = \frac{hdg + 0}{2} = hdg/2\ $
