Question

when a force of 5n acts on a surface it produce a preassure of 500 pa the area of surface then must be .a.10 cm2.b.50 cm2.c.100 cm2.d 0.01 cm2?

Answer 1

Pressure = Force / Area

Area = Force / Pressure
= 5 N / (500 Pa)
= 0.01 m²
= 0.01 × 10⁴ cm²
= 100 cm²

(c) is the correct option.

Answer 2

Answer: c. 100 $\bold{cm^2}$

Explanation:

Pressure is described as an object's physical power. The applied force is perpendicular to the object surface per unit region. Pressure is a force on an item per unit region. It can simply be articulated as P = $\frac{F}{A}$, where F is a force, and A is the region on which it operates.  

$\text { Pressure }=\frac{\text { Strength }}{\text { Area }}$

$\text { Area }=\frac{\text { Strength }}{\text { Pressure }}$

$=\frac{5 N}{500 P a}$

$\text { Area }=0.01 \ \mathrm{m}^{2}$

$\text { Area }=100 \ \mathrm{cm}^{2}$
