Question

A solid body weighs 400N. Calculate the pressure exerted by the solid on a surface, if the area of contact is 40m²

Answer 1

Here, weight of the solid is the force exerted by it on the surface. Area=200/10000=0.02m2

Pressure = Force/Area Pressure = 300/0.02=1500N/m2 or 1500 Pascal

Answer 2

Answer:

The pressure exerted by solid on the surface is 10Pa

Explanation:

Given that,

The weight of the solid body is 400N

Hence the force acting on surface by the solid is nothing but weight of the body.Therefore,

$F=400N$

Also given that the area of contact is 40sq.m.

Therefore,

$A=40m^{2}$

Pressure exerted by solid on surface is the ratio of force to the area of contact.Therefore,

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

Substituting the given values we get

$P=\frac{400}{40} = 10Pa$

Therefore,The pressure exerted by solid on the surface is 10Pa
