What happens to the pressure when the area is reduced while keeping the force same?
Show answer & explanation
Correct answer: B
Explanation
Correct Answer: Pressure increases (Option 2)
- Pressure is defined as the force acting per unit area.
- The formula for pressure is:
Pressure (P) = Force (F) / Area (A) - If the force remains constant and the area is reduced, the pressure increases.
- This is because the same force is concentrated over a smaller surface area, producing a greater effect.
- For example, a sharp knife cuts more easily than a blunt knife because its edge has a much smaller area, creating higher pressure.
- Similarly, needles, nails, and pins have pointed ends so they can produce high pressure with a small force.
- Therefore, reducing the area while keeping the force constant always increases the pressure.
