Question

A liquid of mass 200 gramsexerts a pressure of 0.1 Pa at the bottom of a container. What pressure would it exert if the area of cross - section of the container is doubled ?

Answer 1

• Pressure is inversely proportional to the cross-sectional area: P = F / A
• When the area of cross-sectional is doubled, then pressure exerted will be half as that of initial value since the pressure is inversely proportional to the area of cross-section.
