Question
Pressure is a scalar quantity because ______.
- it is the ratio of force to area and both force and area are vectors.
- it is the ratio of the magnitude of the force to area.
- it is the ratio of the component of the force normal to the area.
- it does not depend on the size of the area chosen.

Solution
b and c
Explanation:
Pressure is defined as the ratio of the magnitude of component of the force normal to the area and the area under consideration.
i.e, P = F/A
Pressure is a scalar quantity. Pressure acts normal on a surface and it is always compressive in nature, therefore, only its magnitude is required for its complete description.
