Why do electric field lines never cross?
Understand the Problem
The question is asking for an explanation of the reason why electric field lines do not intersect. This relates to the concepts of electric fields and their representation through lines that indicate direction and strength of the field at different points in space.
Answer
Electric field lines never cross because it would imply two different directions for the electric field at the same point, which is impossible.
The final answer is that electric field lines never cross because it would imply two different directions for the electric field at the same point, which is impossible.

More Information
Electric field lines are a visual representation of the electric field. They indicate the direction and strength of the field, with their density representing the field's strength. Crossing lines would mean multiple directions at a single point, which violates the uniqueness of the electric field vector.
Tips
A common mistake is to think that electric field lines can cross each other similarly to lines on a graph. This overlooks the vector nature of electric fields, which mandates a unique direction at every point.
