Question

a force of 200 n act on an area of 0.02 m square find the pressure in Pascal

Answer 1

Pressure =Force / Area
=200/0.02
10000

Answer 2

$\huge\textbf{Answer :}$

$158730.158\:pascal\:(Pa)$

OR

$159235.67\:pascal\:(Pa)$

$\underline\textbf{Solution :}$

According to question we have given;

Force = 200 N

Area = 0.02 m²

Area = πr²

= 3.14 × (0.02)² = 0.001256 m²

= 0.00126 m²

We have to find Pressure = ?

So,

Pressure = Force ÷ Area

Pressure = 200 ÷ 0.00126

Pressure = 158730.158 pascal..

OR

If Area = 0.001245 m²

Then, 

Pressure = 200 ÷ 0.001245

Pressure = 159235.67 pascal...
