AThe shape of the containing vessel
BThe depth below the free surface
CThe density of the liquid above the point
DThe acceleration due to gravity at that place
Answer & Solution
Correct answer: A. The shape of the containing vessel
1. P = h * rho * g lists h, rho and g as the only factors.
2. Shape of the vessel does not appear in the formula.
3. So pressure at a depth h is the same regardless of vessel shape.
4. Hence option A is correct.
