Why can electric field lines never cross?
Understand the Problem
The question is asking for an explanation of the principle that electric field lines do not cross each other. This pertains to the unique direction of electric fields at each point in space, which indicates the force a positive charge would experience. If lines were to cross, it would suggest two different directions for the electric field at the same point, which is not possible.
Answer
Electric field lines never cross because the electric field at any point must have a unique direction.
The final answer is that electric field lines never cross because the electric field at any point must have a unique direction, and crossing lines would imply two different directions simultaneously.

More Information
Electric field lines are a conceptual tool used to represent the direction and strength of electric fields. They provide a visual way to understand how the electric field behaves in space around charged objects.
Tips
A common mistake is thinking that field lines could cross and still represent a valid electric field. Remember that this would entail multiple field directions at a single point, which is impossible.
