Example the short answer is if they did cross they would represent a location with two different strong electric field vectors something that can t exist in nature.
The electric lines of force do not intersect why.
This means two directions of the electric field at the point of intersection which is not possible.
2 the electric lines of force always enter or leave the charged surface normally.
Why do electric field lines never intersect answers the tangent at any point on an electric field line gives the direction of the field at that point.
Electric lines of force never intersect each other because at the point of intersection two tangents can be drawn to the two lines of force.
3 electric lines of force can never intersect each other.
Vijay purohit added an answer on 2 8 14 two electric field lines never intersect each other.
1 the electric lines of force start from a positive charge and ends on a negative charge.
Because if they did the field at the point of intersection have two direction which is not possible.
Electric field lines are nothing but the graphical representation of electric field due to a charge in the space.
So if field lines intersect then electric.
4 the electric lines of force cannot pass through a conductor.
