Question

Dorji weighs 1500 n .if the total surface area of the soles of his feet is 0. 5 m2 . What is the pressure exerted by his body o the groung?

Answer 1

Given:-

• Weight (F) = 1500 N

• Area of soles of his feet ,A = 0.5m²

To Find:-

• Pressure exerted by his body on the ground,P.

Solution:-

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

SI Unit of Pressure is Pascal (Pa) .

• P = F/A

Where,

P is the pressure

F is the Force

A is the area

Substitute the value we get

→ P = 1500/0.5

→ P = 15000/5

→ P = 3000 Pa

Therefore,the pressure exerted by his body on the ground is 3000 Pascal.

Extra Knowledge !!

✧ Product of mass and acceleration 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

Question:-

⌬ Dorji weights 1500 N. If the total surface area of the soles of his feet is 0.5 m². What is the pressure exerted by his body on the ground?

⠀

Given:-

• Dorgi Weight = 1500 N
• T.S.A of the soles of his feet = 0.5 m²

⠀

To find:-

• Pressure exerted by his body on the ground.

⠀

Solution:-

⠀

$\star{\boxed{\sf{\orange{S.I~ Unit~ of~ Pressure = Pascal}}}}$

$\star{\boxed{\sf{\purple{S.I~ Unit~ of~ Force = Newton}}}}$

⠀

★ Formula used

• $\sf{P =\dfrac{F}{a}}$

⠀

$\tt\longrightarrow{}$ $\sf{P =\dfrac{F}{a}}$ Means

• P = Pressure
• F = Force
• A = Area

⠀

★ Let's do it ★

$\large{\tt{\longmapsto{P =\dfrac{F}{a}}}}$

$\large{\tt{\longmapsto{P =\dfrac{1500}{0.5}}}}$

$\large{\tt{\longmapsto{P = 3000 pa}}}$

⠀

※ Hence, the pressure exerted by his body on the ground is 3000 pa.
