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

200 Pa

Explanation:

We know that the pressure is represented by the following equation

`P=(F)/(A)`

One of the units of pressure is Pascal

`Pa= (N)/(m^2)`

Data

`F= 400N`

`A= 2m^2`

We substitute in the equation

`P=(F)/(A)\\P=(400N)/(2m^2) \\P= 200 Pa`

Answer 2

200 Pa

Explanation:

The formula to use would be

`P=(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=(F)/(A)\\P=(400)/(2)\\P=200`

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

200 Pa
