Question

Calculate the pressure produced by applying 40N force on a floor measuring 1m wide and 4 m long.

Answer 1

Answer:

10Pa

Explanation:

Pressure equals P=F/A

so P= 40N/4

A=L multiply W

A=4 multiply 1 equals 4m

so pressure becomes 10pa

Answer 2

Given:-

→Force = 40N

→Width of the floor = 1m

→Length of the floor = 4m

To find:-

→Pressure

Solution:-

Here, we can see that the length and width of the floor are given. So firstly, we shall calculate the area of the floor.

Area of the floor = Length×Width

= 4m × 1m

= 4m²

Hence, area of the floor is 4m².

Now, we know that:-

Pressure = Force/Contact area

=> Pressure = 40/4

=>Pressure = 10 Pascal

Thus, the pressure is 10 Pa.

Some Extra Information:-

•Pressure is the force per unit area.

i.e. P = F/A

•S.I. unit of pressure is Pascal or N/m².

•When a force of 1N is acting on an area of 1m², then it is called 1 Pascal.
