If a block of 5 kg is lying on the ground, then the thrust on the surface of the ground due to the weight of the block.

Explanation

To find the thrust on the surface of the ground due to the weight of a block of 5 kg, we can follow these steps:

### Step 1: Understand the Concept of Weight
Weight is the force exerted by gravity on an object. It can be calculated using the formula:
\[ \text{Weight} (W) = m \times g \]
where:
- \( m \) is the mass of the object (in kilograms),
- \( g \) is the acceleration due to gravity (approximately \( 9.8 \, \text{m/s}^2 \) on the surface of the Earth).
