Question

If a force of 100N is applied over an area of 2cm²,calculate the pressure produce

Answer 1

Answer:

• Pressure produced = 50,000 Pa

Explanation:

Given

• Force applied, F = 100 N
• Area of which force is applied, A = 2 cm²

To find

• Pressure produced, P =?

Formula required

• Formula to calculate Pressure

      Pressure = Force / Area

[ Where F is force, P is pressure and A is area ]

• Pressure is known as the force applied per unit area.
• SI unit of pressure : Pascal (Pa)
• 1 Pa = 1 N m⁻²
• Pressure is a scalar quantity.

Solution

Converting area given in cm² into m²

→ Area, A = 2 cm²

→ A = 2 × (1/100)²   m²

→ A = 2 / 10000   m²

→ A = 0.0002 m²

Using formula

→ Pressure = Force / Area

→ P = F / A

→ P = ( 100 ) / ( 0.0002 )

→ P = 1000000 / 2

→ P = 50,000 Pa

Therefore,

• Pressure produced is equal to 50,000 Pascal.

Answer 2

Answer:

• Pressure = 500000pa

Explanation:

Given that,

• Force (F) = 100N
• Area (A) = 2cm²

According To question,

✒ Area (A) = 2/(100)² = 2/10000 = 0.0002m²

We know,

✒ Pressure (P) = Force (F) / Area (A)

[ Put the values ]

➡ P = 100/0.0002

➡ P = 500000pa.
