Question

calculate the force applied on an area 1.36m² exert a pressure of 17 pa.​

Answer 1

Required Answer :

The force applied on the area of 1.36 m² = 23.12 N

Explanation :

In this question we are give that a pressure of 17 pascal is being applied on area of 1.36 m². And we need to calculate the force applied on that area. So, for that we will use the formula of pressure :

$\boxed{\bf P = \dfrac{F}{A}}$

where,

• P denotes the pressure whose S.I. unit is pacal.
• F denotes the force whose S.I. unit is newton.
• A denotes the area whose S.I. unit is metre.

Solution :

We have :

• Area = 1.36 m²
• Pressure = 17 pascal

Need to find :

• Force = ?

Required Solution :

Using formula,

• Pressure = F/A

Substituting the given values :

$\\ : \implies \sf Pressure = \dfrac{Force}{Area}$

$\\ : \implies \sf 17 = \dfrac{Force}{1.36}$

$\\ : \implies \sf 17 \times 1.36 = Force$

$\\ : \implies \sf 17 \times \dfrac{136}{100} = Force$

$\\ : \implies \sf \dfrac{2312}{100} = Force$

$\\ : \implies \sf 23.12 = Force$

Therefore, the force applied on the area of 1.36 m² = 23.12 N

Answer 2

Answer:

• Pressure = 17 pa
• Area = 136 cm ²
• = 136/10,000 = 0.0136 m²
