Question
Complete the following table.
| weight (N) | Area (m2) | Pressure (Nm−2) |
| - | 0.04 | 20,000 |
| 1500 | 500 | - |
Complete the Table
Solution
We know, Pressure = `"Force"/"Area"`
So, using the above formula, we can find one quantity if the other two quantities are given.
| Weight (N) = Force | Area (m2) | Pressure (Nm−2) |
| Weight = Pressure × Area = 20000 × 0.04 = 800 N |
0.04 | 20,000 |
| 1500 | 500 | `"Pressure" = "Weight"/"Area" = 1500/500` = 3 N/m2 |
