No, they must always point from one polarity of charge to the opposite polarity. This would not be true if they crossed.
No. They are are of different nature.
electric lines of force are imaginary lines defined by the paths traced by unit charges placed in an electric field. Lines of force are everywhere parallel to the electric field strength vector. Their principal use is as a convenient means of picturing the geometry of an electric field.
the lines of force are not real. these lines of force are imaginary lines. so we can not touch it.
No, they don't.
1. Electric field lines of force originate from the positive charge and terminate at the negative charge. 2. Electric field lines of force can never intersect each other. 3. Electric field lines of force are not present inside the conductor, it is because electric field inside the conductor is always zero. 4. Electric field lines of force are always perpendicular to the surface of conductor. 5. Curved electric field lines are always non-uniform in nature.
the tangent at any point on an electric field line gives the direction of the field at that point . so if field lines intersect then electric field at will have more than1 direction which is impossible
yes
no according to the law governing forces,it shows that lines of forces can not cross each other
Lines of force don't exist. They can't cross each other because they aren't there. The common (related) demonstration of magnetic lines of force using iron filings works because of the fact that the iron filings become little magnets and line up head to tail. If you photograph them and re-run the experiment you will see that the lines are different, which shows that they are an "artifact" of the magnetic field. No actual lines exist.
yes,the direction of electric force on a charge is tangent of field lines.
No. That would mean that the force vector at some point (the point where the lines cross) goes in two directions at the same time - doesn't make much sense.
