Question

Numerical questions
A force of 25 N acts on an area of 25 cm?. Calculate the pressure produced.
​

Answer 1

Answer:

• 10⁴ Pascal is the required answer.

Explanation:

Given:-

• Force ,F = 25 N

• Area ,A = 25 cm²

To Find:-

• Pressure Produce ,P

Solution:-

Unit Conversion

1 m² = 10⁴ cm²

Therefore, 25 cm² = 25/10⁻⁴ m²

Pressure is defined as the Force per unit area.

• P = F/A

where,

• P denote Pressure
• F denote Force
• A denote Area.

Substitute the value we get

→ P = 25 /25/10⁻⁴

→ P = 25×10⁴/25

→ P = 10⁴ Pa.

• Hence, the pressure produced is 10⁴ Pascal.

Answer 2

Answer:

Given :-

• Force = 25 N
• Area = 25 cm ²

To Find :-

Pressure

Solution :-

Firstly let's convert unit

$\tt \: 25 \: cm = \dfrac{25}{10 { }^{ - 4} }$

Now,

$\huge \bf \: P = \dfrac FA$

$\tt \implies \: P = \dfrac{ \dfrac{25}{25} }{ {10}^{ - 4} }$

$\tt \implies \: P = \dfrac{25 \times 10 {}^{ - 4} }{25}$

$\tt \implies \: P = \dfrac{ \cancel{25} \times 10 {}^{ - 4} }{ \cancel{25}}$

$\frak \red{P = 10 {}^{ - 4} pa}$
