Regarding electric field lines

  1. Sep 10, 2013 #1
    So if you have one positive charge and one negative charge (both with the same arbitrary number of field lines) close to eachother, 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 dont see how this could be however, because neutral atoms still repell eachother 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.
