उत्तर
conservative and field lines do not form closed loops.
Explanation:
Electrostatic fields are conservative due to the fact that the effort performed in relocating a charge between two places is independent of the path taken. Mathematically, `vecv xx vec E = vec 0`, and field lines do not create closed loops as they emanate from positive charges and terminate at negative charges (or stretch to infinity).
