A solid of volume 5 `m^(3)` is immersed completely in a fluid of density 0.5 kg `m^(-3)`. What is the buoyant force acting on it? [Take g = 10 `m//s^(2)`]

Explanation

To find the buoyant force acting on a solid completely immersed in a fluid, we can use Archimedes' principle. According to this principle, the buoyant force (B) is equal to the weight of the fluid displaced by the solid.

### Step-by-Step Solution:

1. **Identify the given values:**
- Volume of the solid (V) = 5 m³
- Density of the fluid (ρ) = 0.5 kg/m³
- Acceleration due to gravity (g) = 10 m/s²
