The lines of force start from the positive charge and end at the negative charge.
Electric field lines never form closed loops
They are always at right angles to the surface of the charge.
The lines of force never intersect each other.
The electric lines of force do not pass through the conductor.
The relative closeness of lines of force in different regions of space gives the idea of the relative strengths of the electric field in different regions.
The electric lines of force contract longitudinally.
The lines of force exert lateral pressure on each other.
