Question

If a force of 20 N is applied over an area of 25cm2, calculate the pressure produced.​

Answer 1

Answer:

8000pascal.

Explanation:

We are given force and area. We've to calculate pressure.

Force = 20N

Area = 25cm²

Convert cm² into m²

$\sf\dfrac{25}{1000}=0.0025m²$

So, the formula for calculating pressure is:-

$P = \dfrac{F}{A} \\ \\ \sf \: Put \: values \: in \: the \: above \: formula \\ \\ \\:\implies{P=\frac{20}{0.0025}} \\ \\ \\\sf\therefore\:{P=8000pa.}$

Answer 2

Answer:

8000 Pa

Explanation:

Given: Force (F) = 20N

Area (A) = 25cm²

First, convert the unit of the area from cm² to m². For this, we will multiply the given area by the factor of 1/10000. This implies that,

Area (A) = 25/10000 = 0.0025m²

We know that, Pressure (P) = Force/Area = F/A

(P) = 20/0.0025 = 8000N/m² or 8000 Pa

Pressure (P) = 8000 Pa

Hence, the pressure exerted by the force is 8000 Pa.
