8. A force of 35 N acts over an area of 7 square meter calculate the pressure
Answers
Given :
→ A force of 35 N acts over an area of 7 square meter
To find :
→ Pressure
Solution :
★ Pressure is the force applied perpendicularlly to an object over a unit area.
The S.I. unit of pressure is Pascal (P).
Formula to calculate pressure :-
- Pressure = F ÷ A
where,
• F denotes the force
• A denotes the area
We have,
• Force = 35 N
• Area = 7 m²
Substituting the given values :-
→ Pressure = 35 ÷ 7
→ Pressure = 5
Therefore, the pressure = 5 Pascal.
Additional Information :
→ Formula to calculate area, when pressure is given :-
- Area = Pressure ÷ Force
The commonly used unit for area → m², cm².
→ Formula to calculate Force, when area and pressure is given :-
- Force = Pressure × Area
The S.I. unit of force → newton (N).
Answer:
Formula to calculate pressure:-
Pressure = F ÷ A
where,
• F means the force
• A means the area
We have,
• Force = 35 N
• Area = 7 m²
Substituting the given values :-
→ Pressure = 35 ÷ 7
→ Pressure = 5
Therefore, the pressure = 5 Pascal.
