Question

Calculate the pressure produced by applying 320N force on a floor measuring 1m wide and 4m long.

Answer 1

Answer:-

First find area of the floor.

• Length=4m
• Breadth=1m

$\\ \tt\longmapsto Area=Length\times Breadth$

$\\ \tt\longmapsto Area=4\times 1$

$\\ \tt\longmapsto Area=4m^2$

• Force=320N

We know that

$\boxed{\sf Pressure=\dfrac{Force}{Area}}$

$\\ \tt\longmapsto Pressure=\dfrac{320}{4}$

$\\ \tt\longmapsto Pressure=80N/m^2$

$\\ \tt\longmapsto Pressure=80Pa$

Answer 2

Given:

Force of 320N is applied on a floor measuring 1m wide and 4m long.

To find:

Pressure exerted?

Calculation:

Pressure is the ratio of applied perpendicular force and the surface area.

$\rm \: Pressure = \dfrac{force}{area}$

$\rm \implies\: Pressure = \dfrac{320}{length \times breadth}$

$\rm \implies\: Pressure = \dfrac{320}{4 \times 1}$

$\rm \implies\: Pressure = \dfrac{320}{4 }$

$\rm \implies\: Pressure = 80 \:Pascal$

So, pressure is 80 Pascal.
