Regarding electric field lines

Click For Summary
SUMMARY

The discussion centers on the behavior of electric field lines in the presence of a positive and a negative charge. It is established that a second positive charge cannot be moved arbitrarily close to the first positive charge without experiencing repulsion. The presence of a negative charge does not neutralize the repulsive force between two positive charges; instead, the second positive charge is attracted to the negative charge while being repelled by the first positive charge. The concept of electric field lines effectively illustrates the direction of force experienced by a test charge in this scenario.

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.
