Question

A skier applies a force of 75N and his skis cover an area of 3m2, calculate the pressure of the skier.

Answer 1

$\huge {\underline{\pink{Given:-}}}$

• Force ,F = 75N

• Area ,A = 3m²

$\huge {\underline{\green{To Find:-}}}$

• Pressure ,P

$\huge {\underline{\blue{Solution:-}}}$

As we know that Pressure is defined as the Force per unit Area.

→ Pressure = $\frac{Force}{Area}$

→ P = $\frac{F}{A}$

Substitute the value we get

→ P = $\frac{75}{3}$

→ P = 25 Pa

Therefore, the pressure of the skier is 25 Pascal.

Additional Information!!

• Product of mass and acceleration is called force.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀OR

•A push or pull of an object is called force.

• SI unit of Force is Newton.

• It is denoted by N.

• Force is vector Quantity i.e., both Magnitude and direction.

Mathematical term

• F = ma

Where,

F is the Force.

m is the mass

a is the acceleration

Answer 2

Explanation:

$\red{ \large \underline\mathfrak{Given} }\: : \:$

• A skier applies a force of 75N

• His skis cover an area of 3m²,

$\green{ \large \underline\mathfrak{To \: find \: }} \: : \:$

• calculate the pressure of the skier.

$\pink{\large \underline\mathfrak{solution \: \: \: } }\: : \:$

Concept :

• pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A.

Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2.

$: \implies \bigstar \: \boxed{\sf \orange{ preasure \: = \frac{force}{area} } }$

$\star \: \underline \boldsymbol{substitute \: all \: values} : \:$

$: \implies \sf \: \: \: \: \: \: preasure \: = \cancel{ \frac{75}{3}} \\ \\ : \implies \sf \: \: \: \: \: \: preasure \: =25$

$\sf \: \therefore \: \underline{the \: preasure \: of \: the \: skier \: is \: 25} \large \: \: \: \dag$
