Question

calcute the pressure extered by a froce 4000N on a area of 20sq.m​

Answer 1

Answer:

Given force = 4000N

and area = 20²m

○ pressure = force

area

= 4000N = 200 Pascal

20m²

I hope it's help you

Answer 2

Given:

✰ Force ( F ) = 4000 N

✰ Surface area ( A ) = 20 m²

To find:

✠ The pressure extered by a force.

Solution:

Pressure:

Pressure is the normal force acting per unit area on a surface.

Total normal force exerted by an object on a given surface is equal to its weight and is known as Thrust.

Therefore, pressure can be defined as the thrust per unit area or the force per unit area. Pressure is exerted by solid liquid as well as gases.

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

✭ Pressure ( P ) = Force (F)/Area (A) ✭

We will put the values of given force and Area on in this formula and after doing the required calculations, we will find out the pressure exerted by the given force on the unit surface area.

➤ Force ( F ) = 4000 N

➤ Surface area ( A ) = 20 m²

➤ Pressure ( P ) = Force (F)/Area (A)

Putting the values in the formula, we have

➤ Pressure ( P ) = 4000/20

➤ Pressure ( P ) = 400/2

➤ Pressure ( P ) = 200 N/m²

∴ The pressure extered by the given force = 200 N/m² or 200 Pa

N.B - the unit of pressure is newton per metre square. This unit is also known as Pascal ( Pa ).
