Question

A man exerts a pressure of 15 Pascal by applying a force of 75 newton on a box . calculate the area over which the force is applied .

Answer 1

Answer:

The Answer is

Area = 5 m

Explanation:

Pressure = 15 Pa ( Pascal )

Force = 75 N

$area \: = \: \frac{force}{pressure}$

$\frac{75}{15}$

= 5

So the answer will be 5 m.

The area over which the force is applied is 5 m.

Answer 2

Answer:

A force of 75 N exerts a pressure of 15 Pa over an area of 5 m².

Explanation:

Definition of pressure:

Pressure is defined as the force acting upon a surface of unit area.

Mathematically, it can be written as:

$Pressure = \frac{Force}{Area}$

Units: The CGS unit of pressure in dyne cm⁻² and the SI unit of pressure is N m⁻² or Pascal (Pa).

Definition of Pascal:

When a force of 1 N acts on a surface having a unit area of 1 m², then the force applied on the surface is termed 1 Pascal.

Calculation:

Given that,
Force (F) acting on the box = 75 N
Pressure (P) applied on the box = 15 Pa
Area (A) of the surface = x (Let)

∴ By the problem,

$P = \frac{F}{A} \\\Rightarrow A = \frac{F}{P} \\\Rightarrow A = \frac{75}{15} \\\Rightarrow A = 5 m^{2}$
