A plece of ice floats in a beaker containing water with a certain fraction inside water. If the density of ice is D and that of water is `rho` find the value of n. What will happen to the level of water when the ice completely melts ?

Explanation

To solve the problem, we need to analyze the situation of the ice floating in water and determine the fraction of the ice submerged in the water, as well as what happens to the water level when the ice melts.

### Step-by-Step Solution:

1. **Understanding the Forces**:
- A piece of ice floats in water due to the balance between the gravitational force acting on it (weight of the ice) and the buoyant force exerted by the water.
- The weight of the ice is given by \( mg \), where \( m \) is the mass of the ice and \( g \) is the acceleration due to gravity.
