Question

3. If a force of 4 N is applied on an area of 4 cm', calculate the pressure.
​

Answer 1

Explanation:

Pressure =Force / Area

Given: Force =4N and Area =4cm²

So, Pressure =4N/4cm²

= 1 N/cm²

Answer 2

100 pascal or N/M²

Explanation:

Given that,

•Force = 4N

•Area = 4cm² = 0.04m²

We need to find,

• Pressure

Solution:

In order to find the pressure, we use the formula: P = F/A

Here,

•P = Pressure,

•F = Force and

•A = Area in metre²

On applying the formula,

⎆ P = 4/0.04

⎆ P = 100 pascal

Hence,

• Pressure exerted = 100 pascal or N/M²
