Question

A brick is 32 cm long,10 cm wide and 10 cm thick. If it weighs 16 Newton and is lying on the ground. Find pressure exerted by brick on the ground.

Open in App

Solution

Converting the units from cm to m, we have the dimensions as-
Length = 0.32 m
Width = 0.1 m
Thickness = 0.1 m
Area in contact with ground = 0.32 x 0.1 = 0.032 m²
We know that, Pressure = Force/Area
= 16/0.032
= 500 N/m²
= 500 Pa.
