Question

calculate the pressure exerted by an object of mass 50 kg to an area of 20 CM square​

Answer 1

Given:

• Mass of object = 50 kg
• Area = 20 cm²

To find:

• Pressure on the surface ?

Calculation:

• Pressure is a scalar quantity characterized by perpendicular force (or thrust) per unit area.

• In other words, pressure is perpendicular force divided by area.

• Its SI UNIT is Pascal (Newton/m²).

Now, we know :

• 20 cm² = 20/10⁴ = 2 × 10^(-3) m².

So, pressure will be :

$P = \dfrac{force}{area}$

$\implies \: P = \dfrac{mg}{area}$

$\implies \: P = \dfrac{50 \times 10}{2 \times {10}^{ - 3} }$

$\implies \: P = 2.5 \times {10}^{5} \: Pa$

So, pressure on the surface is 2.5 × 10⁵ Pascal.
