A rectangular block weighing 180 N has a base area of 0.060 m². It is placed on a horizontal surface. What pressure does the block exert on the surface?
Question 1 Report
A rectangular block weighing 180 N has a base area of 0.060 m². It is placed on a horizontal surface. What pressure does the block exert on the surface?
Answer Details
The pressure exerted by an object resting on a horizontal surface is:
\[ p = \frac{F}{A} = \frac{W}{A} \]
Substituting the values:
\[ p = \frac{180}{0.060} = 3000 \, \text{Pa} \]
The value 10 800 Pa would result from multiplying weight by area (\( 180 \times 0.060 \times 1000 \)), which is not the correct operation. Always divide force by area to find pressure.
