A beaker containing water is placed on the pan of a balance which shows a reading of `M`. A lump of sugar of mass `m` ad volume `v` is now suspend by a thread (from an independent support) in such a way that it is completely immersed in water without touching the beaker and without any overflow of water. How will the reading change as time passes on?

Explanation

To solve the problem, we need to analyze the situation step by step:

### Step 1: Understand the Initial Setup
Initially, we have a beaker filled with water on a balance that shows a reading of \( M \). This reading represents the weight of the beaker and the water inside it.

**Hint:** Consider what the balance measures. It measures the total weight of the beaker and its contents.

### Step 2: Introduce the Lump of Sugar
