Question

A solid exerts a force of 400 N. The pressure exerted by the solid on a surface if the area of contact is 2m2 will be (a) 10 Pa (b) 100 Pa (c) 0.1 Pa (d) 1 Pa
plz help me out to find the answer with these options

Answer 1

Answer:

200 Pa

Step-by-step explanation:

We know that the pressure is represented by the following equation

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

One of the units of pressure is Pascal

$Pa= \frac{N}{m^2}$

Data

$F= 400N$

$A= 2m^2$

We substitute in the equation

$P=\frac{F}{A}\\P=\frac{400N}{2m^2} \\P= 200 Pa$

Answer 2

Answer:

200 Pa

Step-by-step explanation:

The formula to use would be

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

Where

P is pressure [newtons per square meter]

F is force [in Newtons]

A is area [in square meters]

The question gives:

F = 400 newtons

A = 2 square meters

Hence, pressure would be:

$P=\frac{F}{A}\\P=\frac{400}{2}\\P=200$

THe pressure would be 200 newtons/sq m, or 200 Pascals [Pa]

200 Pa
