Question
The field lines do not _____ with each other.
Hint:
An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point.
The correct answer is: Intersect
I
An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point. The relative closeness of the lines at some place gives an idea about the intensity of electric field at that point.
it is not possible that there are two directions of electric field at the same point. Hence, electric field lines never intersect each other is true and this is also a property of electric field lines.
