Question

a force of 15N act on an area of 150 square. cm, find pressure in pascal

Answer 1

Force = 15 N
Area = 150 sq. cm = 0.015 sq. m.

Pressure = force / area = ( 15/0.015 ) Pa
= 1000 Pa

Answer 2

$\star\small\sf\underline\blue{Given:-}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

• A force of 15Newton act on an area of 150 square cm.

$\star\small\sf\underline\blue{Find \: Out:-}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

• The required pressure in Pascal = ?

______________________

$\star\small\sf\underline\blue{Solution:-}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\implies \sf \: Area = 150 \: cm \\ \implies \sf \: Area = 0.015 \: m$

$\footnotesize\bold{\underline{\underline{\sf{\red{Formula\: Used:-}}}}}$

${\underline{\boxed{\sf{Pressure = \dfrac{Force}{Area}}}}}$

$\footnotesize\bold{\underline{\underline{\sf{\red{Putting\: the\: values:-}}}}}$

$\leadsto \sf \: Required\: Pressure = \cancel\dfrac{15}{0.015} \\ \\ \leadsto \sf\red{Required\: Pressure} = \large{\boxed{\bf\blue{1000\:Pa}}}$
