A liid is kept in a glass beaker Which one of the following statements is correct regarding the pressure exerted by the liid column at the base of the beaker?
Explanation
The pressure exerted by a liquid column at the base of a container is governed by the hydrostatic pressure formula: p = ρgh. This equation demonstrates that pressure (p) is directly proportional to the density of the liquid (ρ), the acceleration due to gravity (g), and the height of the liquid column (h). Consequently, the pressure increases linearly with the depth or height of the liquid above the point of measurement. Crucially, hydrostatic pressure depends exclusively on these factors and is independent of the area of the base or the shape of the container. While force is defined as pressure multiplied by area, the pressure itself at a specific depth remains constant regardless of the container's geometry. Therefore, among the given options, the statement that pressure depends on the height of the liquid column is the only correct physical description.
