Why do the electric field lines never cross each other?

Answer: Because at a crossing point the field would have two directions simultaneously, which is impossible.

Solution

At any point the tangent to a field line gives the unique direction of

E

. Two lines crossing would give two tangents, hence two field directions at one point, which cannot occur. So field lines never cross.
