No, they must always point from one polarity of charge to the opposite polarity. This would not be true if they crossed.
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.
No. They are are of different nature.
No, electric field lines do not cross each other. If they did, it would imply that there are multiple directions for the electric field at the same point, which is not possible. The electric field lines always repel or attract each other, but they never cross.
the lines of force are not real. these lines of force are imaginary lines. so we can not touch it.
I think you mean "cross". And furthermore I think you mean the old iron filings around a bar magnet demonstration showing "magnetic lines of force". With all this guessing I propose an answer that your teacher won't like either: They don't cross because they don't exist. To prove this-- Sprinkle the iron filings on paper with a magnet beolw the sheet. Notice that they don't move. Photograph it. Do the experiment again. Photgraph this too and compare the two photos. They will be quite different showing that the "lines of force" are only an artifact of iron filings being sprinkled onto the paper.
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
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 concept of electric lines of force was first introduced by Michael Faraday in the early 19th century. He used the idea to visually represent the electric field around charged objects and to explain how charges interact with each other.
Lines of force never cross because they represent the direction and magnitude of a force at any given point in space. If lines of force were to cross, this would imply that there are two conflicting directions or magnitudes of force at the same point, which is not physically possible.
No, electric field lines cannot cross each other because they represent the direction of the electric field at any given point, and if they were to cross, it would imply that the electric field has multiple directions at that point, which is not physically possible.
no according to the law governing forces,it shows that lines of forces can not cross each other
yes
