A block of wood is kept on a table top The mass of the wooden block is 5 kg and its dimensions are `40cmxx20cmxx10cm`. Find the pressure exerted by the wooden block on the table top if it is made to lie on the table with its sides of dimension (a)`20cmxx10cm`(b) `40cmxx20cm`. Given`g=9.8(m)/(s^2)`.

Explanation

To find the pressure exerted by a wooden block on a table top in two different orientations, we can follow these steps:

### Given Data:
- Mass of the wooden block (m) = 5 kg
- Acceleration due to gravity (g) = 9.8 m/s²

### Step 1: Calculate the Force Exerted by the Block
The force exerted by the block on the table can be calculated using the formula:
