Question

Three open vessels of different shapes have equal base areas and contain the same liquid up to the same vertical height. Which statement about the pressure at the centre of the base of each vessel is correct?

Options

G1 Physics · Accepted Answer

For a static liquid open to the atmosphere, the gauge pressure at depth h is P(gauge) = ρgh. This expression depends on • liquid density ρ, • gravitational acceleration g, • vertical depth h. It does not depend on the shape of the vessel or on the total mass of liquid in the vessel. Since all three vessels contain the same liquid to the same height, the pressure at their bases is the same. Correct option: C.
