# Regarding electric field lines

This would not result in the formation of a neutral unit.In summary, the conversation discusses the concept of field lines and the potential movement of charged particles. The electric field lines represent the direction of force, and in the scenario described, a 2nd positive charge would still be repelled by the 1st positive charge and attracted to the negative charge. This would not result in the formation of a neutral unit.

So if you have one positive charge and one negative charge (both with the same arbitrary number of field lines) close to each other, could you theoretically move a 2nd positive charge as close as desired to the first positive charge without them repelling? Or am i misunderstanding the concept of field lines? Would that negative charge eat up all the positive charge emitted from the first positive charge and just make the one big unit of neutral charge? I don't see how this could be however, because neutral atoms still repell each other because of the electrons on their outside shells...

The electric field lines are a representation of the direction of force that a test charged particle would experience. In your example, the 2nd positive charge would still be repelled from the 1st positive charge and attracted to the negative charge.

## 1. What are electric field lines?

Electric field lines are a visual representation of the direction and strength of an electric field. They are imaginary lines that start at positive charges and end at negative charges, with the density of lines representing the strength of the field.

## 2. How are electric field lines drawn?

Electric field lines are drawn using certain conventions. The lines always start at positive charges and end at negative charges. They are drawn closer together in areas of stronger electric field and farther apart in areas of weaker electric field. The lines also never cross each other.

## 3. What do the direction and spacing of electric field lines indicate?

The direction of electric field lines indicates the direction that a positive test charge would move if placed in the field. The spacing of the lines indicates the strength of the field, with closer lines representing a stronger field and farther lines representing a weaker field.

## 4. Can electric field lines intersect?

No, electric field lines cannot intersect or cross each other. This is because at the point of intersection, there would be two different directions for a test charge to move, which violates the definition of an electric field.

## 5. How do electric field lines change in the presence of multiple charges?

In the presence of multiple charges, the electric field lines will follow the same conventions as before. They will start at positive charges and end at negative charges, with the density of lines representing the strength of the field. However, the lines will also be affected and may curve or bend depending on the relative strengths and positions of the charges.
