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.
