Two cork pieces of same size and mass are dipped in two beakers containing water and oil . The cork floats on water but sink in oil . Why ?

Explanation

To understand why the cork floats in water but sinks in oil, we can break down the problem step by step:

### Step 1: Understand the concept of density
- **Density** is defined as mass per unit volume. Different liquids have different densities. Water has a higher density than oil.

### Step 2: Identify the forces acting on the cork
- When the cork is placed in a liquid, two main forces act on it:
1. **Weight (W)**: The force due to gravity acting downwards, which is equal to the mass of the cork multiplied by the acceleration due to gravity (W = mg).
