elecctri field lines never cross why?

Answer 1

Good question!

After plotting the electric field line patterns for a variety of charge configurations, the general patterns for other configurations can be predicted. There are a number of principles which will assist in such predictions. One such principle is "Electric field lines never cross each other".

Answer 2

Electric field lines should never cross. This is particularly important (and tempting to break) when drawing electric field lines for situations involving a configuration of charges (as in the section below). If electric field lines were ever allowed to cross each other at a given location, then you might be able to imagine the results. Electric field lines reveal information about the direction (and the strength) of an electric field within a region of space. If the lines cross each other at a given location, then there must be two distinctly different values of electric field with their own individual direction at that given location. This could never be the case. Every single location in space has its own electric field strength and direction associated with it; consequently, the lines representing the field cannot cross each other at any given location in space.

Answer 3

electric field lines are the resulting vector of the attractive or repulsive forces by the charges in the system. If you look at a picture like the drawing shown here on wikipedia:
http://en.wikipedia.org/wiki/Electric_field

you can see the pos. and neg. charge and how each little arrow represents the resulting force provided by each charge. If you imagined a vector being drawn right next to any of the drawn vectors, you can think of how the force from each charge would grow or decrease depending on the distance you moved form or toward each charge. Since the force from each charge is based on the distance as well as the magnitude of the charge, you can see how moving around the charges results in almost concentric curves, that bow outward. try picking a point between two drawn vectors and imagining the increase or decrease of the force of attraction from each charge, you should see that your position will reflect a vector that points parallel to the vectors around your vector

Answer 4

basically ,a tangent at any point on electric field lines represent the NET direction of electric field at that point.The degree of closeness of such lines indicates the magnitude at that pt.So if 2 electric f. lines cross then it would mean 2 directions for e.field at that pt which is impossible.

Answer 5

Because each electtric field line is corrosponding to a perticular value of field remain constant on the line. if they r crossing than at intersection point we have two values occuring spontaneously. which is not possible

Answer 6

"an open communicate board for human beings ideals" incorrect. even though gave you that concept? try asking human beings on their 5 or 6th account because of the superb 'open' ness of this communicate board. supply me a ruin, I actual have seen a number of the main bigoted and small minded assaults on freedom of speech in right here. often of the religious style feeling a line is crossed while asked the main trouble-free and easy of questions by a non believer.

Answer 7

because, if they intersect,we will be having 2 values of electric field intensity at a particular point, which of course is not possible!!!

Answer 8

because the +ve field lines repel each other.

Answer 9

the hypothetical north pole cannot be in 2 directions at the same point.( its like saying that when you are standing at a point all the directions around you are same for eg. left)

Answer 10

Yeah, I was going to say everything that Krish said, but she took my answer.
