Question

A force of 800n exerts a pressure of 40n/m2.what area is it acting on

Answer 1

Answer:20 square metres

Explanation:

Pressure=Force÷Area

So, area=force÷pressure

Area= 800÷40

Therefore, Area=20 square metres.

Answer 2

The area at which pressure acting is $20m^2$.

Explanation:

The pressure acting on an object  is given as

$P=\frac{F}{A}$

Here, F is the force applied on an object and A is the area.

Its unit is newtons per square meter, or N/m^2.

Given F = 800 N and P = 40 N/m^2

Substitute the given values, we get

$40 N/m^2=\frac{800N}{A}$

$A=\frac{800N}{40N/m^2}$

$A=20m^2$

Thus, the area at which pressure acting is $20m^2$
