Question

The pressure exerted by an object is 800 Pa. If the area of the object is 0.01 square metre. Find the force acting on the object.

Answer 1

pressure = force / area

800= force / 0.01

Force = 800 x 0.01

Force = 8 N

Answer 2

Answer

• Force = 8 N

Given

• The pressure exerted by an object is 800

• Area of the object is 0.01 square metre

To Find

• Force acting on the object

Concept Used

• Pressure
• It is defined as the force acting per unit area

$\bigstar \bf \;\; P=\dfrac{F}{A}$

• SI unit of Pressure is Pascal , Pa
• SI unit of Force is Newton , N
• SI unit of Area is m²

Solution

Pressure exerted , P = 800 Pa

Area , A = 0.01 m²

Force , F = ? N

Apply formula ,

$\implies \rm P=\dfrac{F}{A}\\\\\implies \rm 800=\dfrac{F}{0.01}\\\\\implies \rm 800\times 0.01=F\\\\\implies \rm 800 \times \dfrac{1}{100}=F\\\\\implies \rm 8=F\\\\\implies \rm F=8\ N\ \;\; \bigstar$

So , Force acting on the object is 8 N .
