Question

WEIGHT OF SCREW IS 0.2N. AREA IS 0.4×10∧-6 M∧2. FIND PRESSURE

Answer 1

Given :-

• Force (F) = 0.2N
• Area of screw (A) = 0.4 × 10^(-6)m²

To find :-

• Pressure

Solution :-

As we know that

→ Pressure = Force/Area

→ Pressure = 0.2/0.4 × 10^(-6)

→ Pressure = 2/4 × 10^(-6) × 10/10

→ Pressure = 1/2 × 10^(-6)

→ Pressure = 10⁶/2

→ Pressure = 10⁵ = 100000

Hence,

• Pressure = 10⁵ N/m²

Extra Information :-

• S.I unit of pressure is N/m² (Pascal)
• S.I unit of Force is Newton
• S.I unit of area is m²

Answer 2

✴ Given :-

• Weight = 0.2 Newton.

• Area = (0.4 × 10)-⁶ m²

✴ To Find :-

• Pressure.

✴ Solution :-

We know that,

Pressure = Force/Area.

⇢ Pressure = 0.2/(0.4 × 10)-⁶

⇢ Pressure = 1/2 × 10-⁶

⇢ Pressure = 10⁵

Hence, Pressure = 100000 Newton/m².
