Charges moving along an electric field:

Click For Summary

Discussion Overview

The discussion centers around the behavior of charges in an electric field, specifically focusing on the movement of positive, negative, and neutral charges. Participants explore the implications of releasing a neutral charge in an electric field and the effects of electric fields on neutral objects versus charged particles.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant notes that a positive charge moves from high to low potential, while a negative charge moves from high to low potential as well, raising the question of what happens to a neutral charge in an electric field.
  • Another participant asserts that neutral charges do not move in an electric field, suggesting that they are unaffected by it.
  • A different viewpoint mentions that while neutrons are neutral and do not experience electric fields, they are not stable on their own and can be split into charged particles under certain conditions.
  • One participant introduces the idea that in macroscopic objects, the constituent charges can separate when placed in an electric field, which can affect the overall electric field around the object.
  • There is a mention of the behavior of dielectrics in capacitors, where neutral materials can influence the electric field and capacitance due to charge separation within them.

Areas of Agreement / Disagreement

Participants generally agree that neutral charges do not move in an electric field, but there is some debate regarding the implications of this in different contexts, such as point particles versus macroscopic objects. The discussion remains unresolved regarding the behavior of neutral charges in various scenarios.

Contextual Notes

There are limitations in the discussion regarding the definitions of neutral charges and the conditions under which they might interact with electric fields. The distinction between classical physics and quantum mechanics is also noted, but not fully explored.

Who May Find This Useful

This discussion may be of interest to students and enthusiasts of physics, particularly those curious about electric fields, charge behavior, and the nuances of classical versus quantum physics.

I'm more curious about what would it be, sort of question, like I know that

When a positive charge is release and moves freely along an electric field line, it moves to a postion of lower potential to lower potential.

If you have a negative charge and release it along an electric field line, it will move from a position of higher potential to lower potential.

Now, my question is that, if I have an neutral charge and release it freely along an electric field line, what would it do?

Would it just stay at a high potential to high potential, or would it not move at all?

Might seem like an odd question, but I just never really hear of neutral charges that often because they really don't do anything or do they. Either way, thanks for any help.

Tey don't do anything. Check some quantum mechanics maybe an electric field strong enough over a neutron can split it into more fundamental particles with charge different than zero
 
Everything always moves from a high potential energy to a lower one, positive or negative charges -> the sign of the charge just effects what the potential is, and where.

Anything neutral is unaffected by an electric field.
A neutron for instance will feel no effect.

side note: neutrons aren't stable by themselves.
 
Also depends if you are talking about macroscopic real objects or point particles. Since this is 'Classical Physics' I'm not sure we can have neutrons ... None the less, in real objects the constituent charges within them tend to separate when immersed in a E field. This reduces the field within the object and increases the field external to it. Which is why an ideal capacitor ( two parallel plates in a vaccum) has less capacitance than two similar plates with a dielectric between them. The dielectric is neutral, but has charges inside it that can separate, making the field more intense at the plates and making more charges move in the plates ... hence more capacitance.

I know this isn't what you asked, but I think this stuff is interesting, and I can't talk to my wife about it .... ;(
