A rectangular block of dimensions 2.0m x 1.0m x 0.5m weighs 200N. calculate the maximum pressure exerted by the block on a horizontal floor.
- 100Nm-2
- 200Nm-2
- 300Nm-2
-
400Nm-2
The correct answer is: D
Explanation
P = \(\frac{wt}{A} = \frac{200}{0.5 \times 1} = 400Nm^{-2}\)
This is because Area is inversely proportional to pressure, so an increase in pressure leads to a decrease in area and vice versa.
