Why do the electric field lines never cross each other?

Advertisement Remove all ads


The tangent to a line of electric field at any point gives the direction of the electric field at that point. If any two lines of electric field cross each other, then at the intersection point, there would be two tangents and hence two directions for electric field, which is not possible. Hence, the electric field lines do not cross each other.
