Question

1.
A brick weighing 40 N having dimensions of 25 cm x 10 cm x 5 cm is kept on a
table with its three different sides one by one. Calculate the pressure exerted in
each of the three cases.
please anyone answer me,I will follow ​

Answer 1

Mass =40N

Case 1: Area of the brick's base surface= 25×10 cm^2

=250 cm^2

Pressure

$= \frac{40}{250} \: pa = 0.16 \: pa$

Case 2: Area of the brick's base surface= 25×5 cm^2

=125 cm^2

Pressure

$= \frac{40}{125} \: pa = 0.32 \: pa$

Case 3: Area of the brick's base surface = 10×5 cm^2

=50 cm^2.

Pressure

$= \frac{40}{50} \: pa = 0.8. \: pa$

[pa:- Pa or pascal]
