The centre of pressure of a liquid on a plane surface immersed vertically in a static body of liquid, always lies below the centroid of the surface area, because

in liquids the pressure acting is same in-all directions

there is no shear stress in liquids at rest

the liquid pressure is constant over depth

the liquid pressure increases linearly with depth
