Question

⭐To compare the pressure exerted by the solid iron cuboid, A student took two cuboids having the same dimension and same nature of material. After performing the experiment with both the cuboids, She found⭐

$a. p1 = 2 {p}^{2}$
$b.p2 = 3 {p}^{1}$
$c.p1 = p2$
$d.p2 = 2 {p}^{1}$
Answer me guys...☺
​

Answer 1

Answer:

pressure = force / area

since two cuboids are of same dimension therefore, P1 = p2

option (c) is your answer

Answer 2

After performing the experiment with both the cuboids, the student found option (c) p1 = p2 to be correct.

• Pressure is defined as force acting per unit area ( P = F / A ).

• Now, force exerted by a cuboid is due to the weight of the cuboid.

∴  Force = weight = mass × acceleration due to gravity

• Since both the cuboids are made of iron, they have the same mass, and therefore, exert the same force.

• Let the pressure exerted by the first and the second cuboid be taken as p1 and p2 respectively by the student.

• Two iron cuboids of same dimensions will also occupy the same area.

• Therefore, two iron cuboids of identical dimensions will exert the same magnitude of force on exactly the same units of area.

• Since force and area are same for both the cuboids, the magnitude of pressure exerted by them is equal.

Hence, p1 = p2.
