A liquid is kept in a glass beaker. Which one of the following statements is correct regarding the pressure exerted by the liquid column at the base of the beaker ?
The pressure depends on the area of the base of the beaker
The pressure depends on the height of liquid column
The pressure does not depend on the density of the liquid
The pressure neither depends on the area of the base of the beaker nor on the height of liquid column

– P is the pressure
– ρ (rho) is the density of the liquid
– g is the acceleration due to gravity
– h is the height of the liquid column
– It is independent of the shape of the container or the area of the base, as long as the height and density are the same (this is known as the hydrostatic paradox).
