Question

A force of 25(N) act on a surface of area 125cm². calculate the pressure exerted on a surface.
​

Answer 1

Answer:

$\frac{1}{5}$

Explanation:

Given-

Force(F)=25N

Area(a)=$125cm^{2}$

to Find-

Pressure(pa)=?

Formula Used-

pa=$\frac{F}{a}$

Calculations-

pa=$\frac{25}{125}$

pa=$\frac{1}{5}$

Answer 2

Given :-

• Force = 25 N

• Surface area = 125 cm² = $\dfrac{125}{10000}$m²

Solution : Force = Pressure × Area

• 25 N = P × $\dfrac{125}{10000}$

• P = $\dfrac{25 × 10000}{125}$

• P = 2000 Pa

• P = 2 × 10³ N/m²
