Coulumb's Law at 1 light year distance

Click For Summary

Discussion Overview

The discussion revolves around the implications of Coulomb's Law when applied to particles separated by a distance of one light year. Participants explore both the practical and theoretical aspects of the force at such a distance, considering the inverse square law and potential delays in force transmission.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants suggest that the force would be very weak at one light year due to the inverse square law.
  • One participant questions the meaning of "what happens" to the force, seeking clarification on the inquiry.
  • Another participant proposes that the original poster (OP) may be considering the delay in force transmission at such a distance.
  • There is a suggestion that if the charges on the particles were extremely high, the force might not be as weak.
  • Some participants express uncertainty about the OP's intent and suggest waiting for further clarification from them.

Areas of Agreement / Disagreement

Participants generally agree that the force would be weak at one light year due to the inverse square law, but there is no consensus on the OP's specific question or intent. Multiple interpretations of the inquiry remain unresolved.

Contextual Notes

There are limitations in understanding the OP's question, particularly regarding the implications of distance on force and the potential for delays in force transmission. The discussion does not resolve these ambiguities.

Hi,
What happens to the force when the particle are kept at 1 light year distance. I agree practically the force would be very weak because of inverse square law, theoretically what happens to the force?

Have you tried plugging that distance into the formula for Coulomb's law?

I don’t understand the question. If someone asked “what happens to the force at 1 m distance?” what would be the answer you are looking for? What are you looking for with the word “happens”?

You already have the answer within the question. It would be very weak unless the charge on each particle was extremely high.

Could he be wondering about the delay at 1ly?

If he means Coulomb's Law literally then I don't think so, no, because that's the field of an eternal stationary charge and it is unchanging throughout all of space. Maybe OP does mean something else, but he hasn't been seen since posting this so I reckon we should wait until he comes back before going too far off on a tangent. (I'm a shoo-in for this year's hypocrisy award with this...)

Stand aside, young man - I'm ahead of your in the line.

It could be that. I don’t know, which is why I asked.

One minute? Looks like a "drive-by" to me.
