Gauss' law in one-dimensional space

AI Thread Summary
In a one-dimensional closed loop with positive and negative charges, Gauss's law is not applicable since it requires a three-dimensional volume enclosed by a closed surface. Instead, the electric field in this scenario should be determined by the superposition principle, which involves calculating the electric fields produced by each charge individually and then combining them. The electric field will vary along the loop depending on the positions of the charges. Understanding this concept is crucial for analyzing electric fields in lower dimensions. The discussion emphasizes the importance of applying the correct principles when dealing with electric fields in one-dimensional spaces.

Hello I am new here.

Here is the situation:

There is a 1-dimensional closed loop and this loop spans a one-dimensional space.

If there are a +ve and a -ve charge at rest on some points in the loop, what should be the electric field in the loop?

The only thing I can think of is Gauss' law. But I went into trouble because I don't know how to apply it in a 1-dim space.

BTW, Please don't give too detailed proof to me. I got to solve it by myself. I just hope anyone can give me some hint.

I am a physics undergrad.

Thanks in advance

Gauss's law does not apply in one-dimension or even two. You need a volume enclosed by a closed surface to apply Gauss's Law. From your description, it appears you have a line segment with two charges on it which requires superposition of the electric fields generated by each charge,
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
