# Equal mass of three liquids are kept in three identical cylindrical vessels A, B and C. The densities are ρA, ρB, ρC with ρA < ρB < ρC. The force on the base will beA.maximum in vessel AB. maximum in vessel BC. maximum in vessel CD. equal in all the vessels.

Let the mass of the liquids be “m”, and the base area be “a”.

Volume, , where 𝜌 is the density of the liquid. And where h is the height of the liquid. Therefore,

; ;

Now the pressure is given by

Similarly, and .

Hence, the pressure is same in all the three cases.
