If pressure is a scalar quantity and I can't add or subtract different magnitudes of pressure acting on the same object, what if I divide the NET force by area? what quantity would that give me. I suppose it would give me the " net " pressure but that contradicts the fact that I can't add or subtract individual pressure values on the same object. And I'm not talking about hydrostatic pressure
Explanation:
Pressure is a scalar quantity, not a vector quantity. It has a magnitude but no direction associated with it. Pressure acts in all directions at a point inside a gas. At the surface of a gas, the pressure force acts perpendicular to the surface.
Although pressure itself is a scalar, we can define a pressure force to be equal to the pressure (force/area) times the surface area in a direction perpendicular to the surface. The pressure force is a vector quantity.
I think now you can arrive on your answer,
