Question

a Brick having wt 30N is 21cm long,10 cm wide , and 6 cm high. the face of the brick on the ground having dimension 21cm , 6cm is in contact with ground. Find the pressure exerted by the ground​

Answer 1

Answer:

Pressure =2830 N

Explanation:

Given that :weight = 30 N

Area of space on which pressure is exerted =21cm×6cm

=106 /100×100 m^2

=. 0106m^2

SOLUTION:

As we know that

Pressure = normal force / area

Here the weight of body will be act as the normal force because weight act in the normal direction

pressure = 30/.0106

= 2830 n/m²
