A fly was sitting on a block. A man draws a circle of area , thus enclosing the fly. He then applies a force of 20N and kills it with a flat stick. Calculate the pressure on that area.
Step1: Given data
The area of the circle is .
Force is
Step2: Formula used
Step3: Calculating pressure
Pressure is the amount of force applied normally to the surface area of an object. In other words, it is the force applied per unit area.
Given area is
Substituting the value of area and force in the formula
Hence, the pressure on that area is
