  1. Electric field lines contract longitudinally due to the attractive force between opposite charges, which pulls the field lines together. This contraction represents the tendency of opposite charges to come closer, reducing potential energy and maintaining the natural behavior of electric fields.
    (a) Attraction between unlike charges.
