The force acting on a unit area is called
-
surface tension
-
buoyant force
-
pressure
-
thrust
C
Correct answer
Explanation
Pressure is defined as force per unit area (P = F/A). Surface tension is the force per unit length at a liquid's surface. Buoyant force is the upward force on a submerged object. Thrust is the total force acting perpendicular to a surface, not normalized by area.
