1 the electric lines of force start from a positive charge and ends on a negative charge.
The electric lines of force do not intersect why.
4 the electric lines of force cannot pass through a conductor.
Electric field lines are nothing but the graphical representation of electric field due to a charge in the space.
Lines of force represent the strength of the electric field at any given point.
Because if they did the field at the point of intersection have two direction which is not possible.
Why do electric lines of force never cross.
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.
No two equipotential surface never intersect each otherm.
This means two directions of the electric field at the point of intersection which is not possible.
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.
So if field lines intersect then electric.
2 the electric lines of force always enter or leave the charged surface normally.
