Step 1
In which direction does the net force always act?
Answer
The net force exerted by a fluid under pressure acts at right angles to any surface. This is due to the nature of pressure in fluids, which is exerted uniformly in all directions. Consequently, regardless of the orientation of the surface in contact with the fluid, the force will always be perpendicular to that surface. Therefore, the correct answer is:
A. At right angles to any surface.
