CBSE · Class 12 · Physics · Electric Charges and FieldsWhy can two electric field lines never intersect each other? Explain.

Two electric field lines can never intersect each other because if they intersect at a point, then at that point of intersection, two tangents can be drawn. This means that the electric field intensity at that single point would have two different directions simultaneously, which is physically impossible as a field vector can point in only one unique direction at any location.
