Question

a force of 15N acts on an area of 50 cm² find the pressures in Pa​

Answer 1

Explanation:

pressure = force /area

force = 15N

area = 50 cm² or

0.005m

pressure = 15/0.005

= 3000 pa

Answer 2

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

⠀⠀⠀⠀⠀⠀⠀⠀⠀

• A force of 15Newton act on an area of 50 square cm.

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

⠀⠀⠀⠀⠀⠀⠀⠀⠀

• The required pressure in Pascal = ?

______________________

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

⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\implies \sf \: Area = 50 \: cm^2\\ \implies \sf \: Area = 0.005 \: m$

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

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

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

$\leadsto \sf \: Required\: Pressure = \cancel\dfrac{15}{0.005} \\ \\ \leadsto \sf\red{Required\: Pressure} = \large{\boxed{\bf\blue{3000\:Pa}}}$

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

• The required pressure in Pascal is 3000 Pa.
