The force exerted by a stationary liquid on an inclined rectangular surface at rest in the liquid acts normally to the surface. This is due to the pressure exerted by the liquid, which is perpendicular to the surface. The force is not exerted equally at all points on the surface, as the pressure varies with depth. It also does not act parallel to the surface or vary inversely with depth. The density of the liquid affects the magnitude of the force, so the force is not independent of the density of the liquid.
