Question

A Solid body weights 150N when placed on a surface the area of a contact is 8m square Find the pressure exerted by the solid body on the surface

Answer 1

Given:

Weight of the solid body = 150 N.

Area of contact = 8 m².

To find:

The pressure exerted by the solid body on the surface.

Solution:

The solid body weighs 150 N.

∴ Force applied by the body = 150 N.

The surface area in contact of the solid body = 8 m².

We know that,

$Pressure = \dfrac{Force}{Area} \\\\= \dfrac{150}{8} \\\\= 18.75 pascal$

∴ The pressure applied by the body is 18.75 pascal(Pa)

Answer:

            The pressure applied by the body is 18.75 pascal(Pa).
