Answer:
Step-by-step explanation:
Pressure = 20 N/m²
Diameter = 2 cm
Therefore, Radius = 1 cm.
∴ Area = πr² = 22/7 × (2/2)²
= 22/7 cm². = 22/7 × 10⁻⁴ m².
Now, Using the Formula,
Pressure = Force/Area
Therefore, Force = Pressure × Area
∴ Force = 20 × 22/7 × 10⁻⁴
∴ Force = 6.286 × 10⁻³ N.
Hope it helps.
