Explanation:
Formula
Force
- It will be constant in both cases as mass remains the sam
- F = mg = 2 x 10 = 20 N
Case (i) : Maximum Pressure
- Area has to be minimum
- A = 10 x 20 = 200 cm² ≅ 0.02 m²
- P = F/A = 20/2 x 10⁻² = 1000 Pa
Case (ii) : Minimum Pressure
- Area has to be maximum
- A = 30 x 20 = 600 cm² ≅ 0.06 m²
- P = F/A = 20/6 x 10⁻² = 3.33 x 10² = 333 Pa
