Question

The three vessels shown in figure have same base area. Equal volumes of a liquid are poured in three vessels. The force on the base will be

• A. Maximum in vessel A
• B. Maximum in vessel B
• C. Maximum in vessel C
• D. Equal in all the vessels

Answer 1

The correct option is C

Maximum in vessel C

Equal volume of liquid is poured in A, B and C given that base area is equal and you know,

V=A$\times$h

i.e., volume = area $\times$ height

as is C, the height gradually reduces, therefore the height of water column is maximum in C.and you know, pressure at the base will be

P=$P_0$+pgh

Where $P_0$ = Atmospheric pressure

Therefore the force on the base will be maximum in vessel 'C'
