The correct calculation for the pressure exerted by the wooden piece should be considered.
Pressure is defined as force per unit area.
The wooden piece has a weight (force) of 5 N and lies on a face with dimensions 5 cm x 2 cm, giving an area of 5 × 2 = 10 cm². Therefore, the pressure exerted by the wooden piece is calculated as 5 N / 10 cm² = 0.5 N/cm². The correct answer is option 3, which is 0.5.

Understanding Pressure
Pressure is defined as the force exerted per unit area. In this case, we need to calculate the pressure exerted by the wooden piece on the surface it rests upon.
Given Data
- Weight of the wooden piece: 5 N
- Dimensions of the wooden piece: 5 cm x 3 cm x 2 cm
- Area in contact with the surface: 5 cm x 2 cm
Calculating the Area
To find the area of the base that is in contact with the surface, we multiply the dimensions of this face:
- Area = Length x Width = 5 cm x 2 cm = 10 cm²
Calculating Pressure
Now, we can calculate the pressure exerted by the wooden piece using the formula:
Pressure = Force / Area
Substituting the values:
- Force = 5 N
- Area = 10 cm²
Pressure = 5 N / 10 cm² = 0.5 N/cm²
Conclusion
The pressure exerted by the wooden piece on the surface is 0.5 N/cm².
Thus, the correct answer is option 'C'.
