Electric field lines can intersect if charges are equal
Electric field lines can form closed loops in the presence of conductors
Two electric field lines of force can never intersect (correct)

Flashcards

Electric field lines - starting point

Electric field lines always begin at a positive charge and end at a negative charge.

Electric field line tangent

The tangent to an electric field line at any given point represents the direction of the electric field at that point.

Electric field line density

The density of electric field lines indicates the strength of the electric field: closer lines mean a stronger field.

Electric field lines - intersection

Two electric field lines will never cross each other. If they did, it would imply multiple directions for the field at that point, which is impossible.
