Two copper vessels A and B have the same base area but of different shapes. A takes twice the volume of water as that B requires to fill upto a particular common height. Then the correct statement among the following is: (a) Vessel B weighs twice that of A. (b) Pressure on the base area of vessels A and B is same. (c) Pressure on the base area of vessels A and B is not same. (d) Both vessels A and B weigh the same.

Answer: (b). Pressure on the base depends only on the liquid height: P = P₀ + ρ g h, not on the vessel shape or volume. Both are filled to the same height, so the pressure on the bases is the same. A holds more water, so A (with water) weighs more; (a) and (d) are wrong. So the answer is (b).

Pressure in a Fluid

Two copper vessels A and B have the same base area but of different shapes. A takes twice the volume of water as that B requires to fill upto a particular common height. Then the correct statement among the following is:

Show answer and solution

Answer: (b)

Pressure on the base depends only on the liquid height: $P = P_0 + \rho g h$ , not on the vessel shape or volume.
Both are filled to the same height, so the pressure on the bases is the same.
A holds more water, so A (with water) weighs more; (a) and (d) are wrong.
So the answer is (b).
