The force acting on a unit area of a surface is called:

Correct option is C

Ans. (c)
Sol. Pressure is defined as the force applied per unit area. Mathematically, it is expressed as:
· Pressure = Force / Area Pressure is typically measured in Pascal (Pa) in the SI system.
Explanation of each option:
· (a) Friction – The resistance to motion that occurs when two surfaces rub against each other, not related to force on unit area.
· (b) Tension – Refers to the pulling force transmitted through a string, rope, or other object, not directly related to surface area.
· (c) Pressure – Correct answer. The force per unit area applied on a surface.
· (d) Gravity – The force of attraction between masses, not the force applied to a surface.
