Concept:Pressure is a scalar quantity because it is defined as the magnitude of the normal component of force per unit area, and fluid pressure at a point acts equally in all directions, having no associated direction.
Explanation:Pressure is given by
P=AF⊥​​, where
F⊥​ is the magnitude of the force acting perpendicular to the area.
Even though force is a vector, only its normal component is used, and that component is taken as a scalar magnitude.
In a fluid at rest, the pressure at a point is the same in all directions, meaning it has no specific directional property.
Thus, pressure does not obey vector addition rules and is treated as a scalar quantity.
Answer:Option C: It is the ratio of component of force (normal to area) to area.
