Question

The same amount of pressure is applied to two different objects with different surface areas. In this scenario, which of the following statements is correct?

• A. Both the surfaces experience the same force.
• B. The object having more surface area experiences more force.
• C. The object having less surface area experiences more force.
• D. The object having more surface area experiences less force.

Answer 1

The correct option is C The object having less surface area experiences more force.

It is mentioned that the pressure applied on two objects is the same.

From definition of pressure,
$\text{Pressure}=\frac{\text{Thrust}}{\text{Area}}$
$\text{Thrust}=\text{Pressure}\times \text{Area}$
It is given that pressure is constant.
$\text{Thrust}\propto \text{Area}$

​​​​​​​So, the object with more surface area will experience a greater amount of force.
