Question
The three vessels shown in the following figure have same base area. Equal volumes of a liquid are poured in the three vessels. The force on the base will be
Options
maximum in vessel A
maximum in vessel B
maximum in vessel C
equal in all the vessels

Solution
maximum in vessel C
Here, the height of the liquid column is maximum in vessel C. Thus, the force on the base of vessel C, i.e., F = P0 + hρg where P0 is atmospheric pressure, is maximum.
