Question

Find the pressure in N/cm2 exerted by a force of 36 N on an area of 0.9 cm2.

Answer 1

$\LARGE{ \underline{ \red{ \sf{Required \: answer:}}}}$

In this question, we have to find the pressure exerted by a force and the area is also given.

Pressure is calculated by force (Thurst) applied on unit surface area.

$\because{\large{ \boxed{ \sf{P = \frac{F}{A}}}}}$

GiveN:

• Force applied by the books = 36 N
• Area of contact = 0.9 cm²

━━━━━━━━━━━━━━━━━━━━

By using formula,

⇛ P = F / A

Plugging the given values,

⇛ P = 36 N / 0.9 cm²

⇛ P = 360/9 N/cm²

⇛ P = 40 N/cm²

So, the pressure exerted by force on the given area:

$\therefore{ \LARGE{ \boxed{ \red{ \bf{ 40 \: N/{cm}^{2}}}}}}$

And we are done !!

Answer 2

Answer:

4000 pa

Step-by-step explanation:

Force = 36

1. area =0•9 cm² so pressure = 36*10^-4
2. = 4000 pa
