Question

calculate the force applied on an area of 81m² to exert a pressure of 10 pascal​

Answer 1

Answer:

F=Pressure/area

Explanation:

F=P

A

F=10

81

F= 8.1 N

Answer 2

Given:

✰ Surface area (A) = 81 m²

✰ Pressure (P) = 10 Pa

To find:

✠ The force applied.

Solution:

Pressure:

➛ The normal force acting per unit area on a surface is called pressure.

If F is the normal force applied and A is a normal surface area, then the pressure P exerted on this area is given by,

✭ Pressure (P) = Force (F)/Surface area (A) ✭

Here in this question, we need to find the force applied.

✭ F = P × A ✭

Where,

• F is the normal force applied.
• P is the pressure exerted on the surface area.
• A is the normal surface area.

Putting the values in the formula, we have:

➤ F = 10 × 81

➤ F = 810 N

∴ The force applied = 810 N
