Question

Calculate the pressure in pascals if a 400N force is applied to an area of 0.5m².

Answer 1

Answer:

800

Explanation:

P=f/a

p=400/0.5=800pa

Answer 2

The pressure exerted by the box on the table is 800 Pa.

Explanation:

Given that,

Force applied on the object, F = 400 N

Area of cross section of the object, $A=0.5\ m^2$

We need to find the pressure exerted by the object per unit area. It is given by the net force acting on the box per unit area. Its formula is given by :

$P=\dfrac{F}{A}$

$P=\dfrac{400\ N}{0.5\ m^2}$

P = 800 Pa

So, the pressure exerted by the box on the table is 800 Pa. Hence, this is the required solution.
