Question

A brick of weight 30 newton is 20 cm long, 10 cm wide and 6 cm high. The force of dimension 20 cm and 6 cm is in contact with the ground. Find the pressure on the ground.
Explain and type the answer please. Don't just simply give the direct answer please. Please give me the answer fast.​

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

=. 0106 m^2

Solution :

As we know that

pressure \: = \frac{normal \: force }{area}pressure=

area

normalforce

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

\begin{gathered}pressure = \frac{30}{.0106} \\ = 2830 \frac{n}{ {m}^{2} }\end{gathered}

pressure=

.0106
