Question

a pressure of 20 N/m² is acting on a circular area of diameter 2cm. The normal force acting on circular area is​

Answer 1

$\textbf{\underline{\underline{ANSWER}}}$

$\textbf{\underline{Given}}$

Pressure = 20 N/m^2

diameter = 2 cm = 0.02 m

$\textbf{\underline{To\:Find}}$

Force = ?

$\textbf{\underline{Solution}}$

We know that

Pressure = Force/area

20 = force/ 3.14 × 0.0001

Force = 20 × 0.0001 × 3.14

Force = 0.00628 N
