Question

Q2: A girl weighing 400 Newton has shoes with wedge heels. Each heel has an area of
0.0003 m². If girl puts all her weight on one heel, what pressure does she put on the floor?

Answer 1

Given

• Weight = 400 N
• Area of heel = 0.0003 m²

To Find

• Pressure if all the weight is on one heel

Solution

● Pressure = Force/Area

● As the Area reduce the pressure increases and as the area increase the pressure also decrease

● P ∝ 1/A

✭ Pressure Applied :

→ Pressure = Force/Area

→ Pressure = 400/0.0003

→ Pressure = 1333333.33 Pa

━━━━━━━━━━━━━━━━━━━━━━

• Note that Weight = Force applied. Weight is equal to the force applied by the body on the ground

Answer 2

Answer:

Given :-

• A girl weighing 400 N has shoes with wedge heels. Each heel has an area of 0.0003 m².

To Find :-

• What is the pressure does she put on the floor.

Formula Used :-

✦ Pressure = Force ÷ Area ✦

Solution :-

Given :

• Force = 400 N
• Area = 0.0003 m²

According to the question by using the formula we get,

⇒ Pressure = 400 ÷ 0.0003

➠ Pressure = 1333333.33 Pascal

∴ The pressure does she put on the floor is 1333333.33 Pascal .
