Question

Effect of a force depends on the

• A. Volume of the object on which the force acts
• B. Area of the object on which the force acts
• C. Displacement caused by the force
• D. None

Answer 1

Answer: (B)

Area of the object on which the force acts

Pressure is a measure of effect of force on an object.

Pressure is defined as force per unit area, that is,

$P=\frac{F}{A}$

Hence the effect of force depends upon the area upon which it acts. Smaller area would have greater effect for equal amount of applied force.
