Pressure on the Table Top

To find the pressure on the table top when the wooden block is placed on it, we need to calculate the force exerted by the block on the table and then divide it by the area of contact between the block and the table.

Dimensions of the Block:
- Length (L) = 50 cm
- Breadth (B) = 25 cm
- Height (H) = 10 cm

Mass of the Block:
- Mass (m) = 4 kg

Area of Contact:
- When the block is kept with its surface measuring 50 cm × 25 cm on the table, the area of contact between the block and the table is given by the product of length and breadth.
- Area of contact (A1) = L * B

Force exerted by the Block:
- Force (F1) = mass * acceleration due to gravity
- F1 = m * g, where g is approximately 9.8 m/s²

Pressure on the Table:
- Pressure (P1) = Force/Area of contact
- P1 = F1/A1

Calculations:
- Area of contact (A1) = 50 cm * 25 cm = 1250 cm²
- Force (F1) = 4 kg * 9.8 m/s² = 39.2 N
- Pressure (P1) = 39.2 N / 1250 cm²

Explanation:
When the wooden block is kept with its surface measuring 50 cm × 25 cm on the table, the pressure exerted on the table top is calculated by dividing the force exerted by the block (which is equal to the weight of the block) by the area of contact between the block and the table.

Pressure on the Table Top (II)

To find the pressure on the table top when the block is placed with its surface measuring 25 cm × 10 cm on the table, we follow the same steps as above.

Area of Contact:
- When the block is kept with its surface measuring 25 cm × 10 cm on the table, the area of contact between the block and the table is given by the product of length and breadth.
- Area of contact (A2) = L * B

Force exerted by the Block:
- Force (F2) = mass * acceleration due to gravity
- F2 = m * g, where g is approximately 9.8 m/s²

Pressure on the Table:
- Pressure (P2) = Force/Area of contact
- P2 = F2/A2

Calculations:
- Area of contact (A2) = 25 cm * 10 cm = 250 cm²
- Force (F2) = 4 kg * 9.8 m/s² = 39.2 N
- Pressure (P2) = 39.2 N / 250 cm²

Explanation:
When the wooden block is kept with its surface measuring 25 cm × 10 cm on the table, the pressure exerted on the table top is calculated by dividing the force exerted by the block (
