Vedclass · Answer

(A) The pressure at the base of a vessel is given by $P = \frac{F}{A}$,where $F$ is the force exerted by the liquid on the base and $A$ is the area of the base.Since the vessels are identical,the area $A$ of the base is the same for all three vessels.The force $F$ exerted by the liquid on the base is equal to the weight of the liquid,$F = mg$.Since the masses $m$ of the liquids are equal and the acceleration due to gravity $g$ is constant,the force $F$ is the same for all three vessels.Therefore,the pressure $P = \frac{mg}{A}$ is equal in all three vessels,regardless of the density of the liquids.

Three identical vessels are filled with equal masses of three different liquids $A, B$ and $C$ $(\rho_A > \rho_B > \rho_C)$. The pressure at the base will be
