Electric field lines contract lengthwise because they represent the force experienced by a positive test charge in the field. This contraction indicates the attraction between opposite charges, as field lines always originate from positive charges and terminate at negative charges, pulling toward each other.
Thus, the correct answer is (b) Attraction between opposite charges.

    1. Electric field lines contract lengthwise, indicating attraction between opposite charges. This contraction represents the tendency of unlike charges to pull toward each other, minimizing potential energy. It visually demonstrates the force between opposite charges, reinforcing the fundamental principle of electrostatic attraction, where positive and negative charges experience mutual force drawing them together, shaping the electric field accordingly.
