Question

a force of 200N acts on an area of 0.02 metre sq. find the pressure in pascal

Answer 1

pressure = force/ area m^2

pressure = 200/0.02

pressure = 10000 n/m^2

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...
