What is the thrust on unit area called?

Correct option is D

The correct answer is (d) Pressure.
· Pressure is defined as the thrust (force) exerted per unit area. It is mathematically expressed as:
Pressure=
The SI unit of pressure is the Pascal (Pa), which is equivalent to one Newton per square meter (N/m²).
Explanation of Other Options:
· Volume : The amount of space occupied by an object, not related to thrust or area.
· Surface Area : The total area of the surface of a three-dimensional object, not related to thrust per unit area.
· Density : Mass per unit volume, not related to force or pressure.
