Amongst which of the following statement is correct about hydrostatic forces on surfaces?

10. Amongst which of the following statement is correct about hydrostatic forces on surfaces?

1. The direction of the hydrostatic force depends on the shape of the surface
2. The center of pressure on a submerged vertical surface is always at the midpoint of the surface
3. The hydrostatic force is always equal to the pressure at the bottom of the fluid
4. The hydrostatic force is independent of the fluid density and depth

Answer: A) The direction of the hydrostatic force depends on the shape of the surface.

Explanation:

The direction of the hydrostatic force on a surface depends on the shape of the surface. It acts perpendicular to the surface, and its magnitude is determined by fluid density, depth, and the shape of the surface.
