How will you show that electrons are negatively charged particle ?

Explanation

To demonstrate that electrons are negatively charged particles, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cathode Rays**:
- Cathode rays are streams of particles that are emitted from the cathode (the negative electrode) in a vacuum tube. These particles are known to be electrons.

2. **Direction of Cathode Rays**:
- When a voltage is applied across the cathode and anode, the cathode rays travel from the cathode to the anode. This movement is from the negative electrode (cathode) to the positive electrode (anode).

3. **Attraction to Anode**:
- Since the anode is positively charged, it will attract particles that have a negative charge. This is a fundamental property of electric charges: opposite charges attract.

4. **Conclusion**:
- Because the cathode rays (which are streams of electrons) are attracted to the positively charged anode, we can conclude that electrons must carry a negative charge. If they were positively charged, they would be repelled by the anode.

### Final Statement:
Thus, the behavior of cathode rays in a vacuum tube demonstrates that electrons are negatively charged particles, as they travel from the negative cathode to the positive anode and are attracted to the anode.
