Why Does an Electron Slow Down Near a Charge?

  • Thread starter Laurie01
  • Start date
In summary, the question asks whether an electron moving towards a source charge will slow down, and what the identity of the source charge could be. The answer states that the identity cannot be inferred from the movement alone, but only from the fact that the electron slows down. The conclusive answer is that the source charge is most likely an electron.

Question: An electron is moving towards a source charge, and slows down. What is the source charge (a proton or an electron)?

I feel like this question is pretty vague (because it says it moves towards the charge (making me think proton), but yet it slows down (making me think electron)) and I'm wondering how you guys would answer it.

You cannot infer the identity of the source charge from the fact that an electron is moving towards it. It could be moving towards it due to some external agent. You can only infer the identity of the source charge from the fact that it slows down.

So it would be an electron.

Does an electron ever slow down as it approaches a proton in terms of it slowing down to fall into orbit?
 

1. What is the Proton/Electron Problem?

The Proton/Electron Problem is a fundamental question in physics that seeks to understand the origin and behavior of subatomic particles such as protons and electrons.

2. Why is the Proton/Electron Problem important?

The Proton/Electron Problem is important because it helps us understand the fundamental building blocks of matter and the forces that govern their interactions. It also has implications for understanding the evolution of the universe and the nature of energy and matter.

3. What is the current understanding of the Proton/Electron Problem?

The current understanding of the Proton/Electron Problem is based on the Standard Model of particle physics. This model describes protons and electrons as elementary particles, and explains their properties and interactions through the exchange of other particles and forces.

4. Are there any unsolved aspects of the Proton/Electron Problem?

Yes, there are still some unsolved aspects of the Proton/Electron Problem. For example, scientists are still trying to understand the difference in mass between protons and electrons, and why there are more matter particles than antimatter particles in the universe.

5. How are scientists studying the Proton/Electron Problem?

Scientists are studying the Proton/Electron Problem through a combination of theoretical and experimental approaches. They use advanced particle accelerators and detectors to study the behavior of subatomic particles and test the predictions of the Standard Model.
