Electric field lines of force A exist everywhere exist only in the immediate vicinity of electric charges YOUR ANSWER exist only when both positive and negative charges are near one another D are imaginary YOU MISSED.
Where does electric lines of force exist?
Exist only in the immediate vicinity of electric charges.
Can electric field lines start anywhere?
Electrical field lines can only begin and terminate at charges. Here, Φ is the flux through a closed surface, and Q is the amount of charge enclosed by that surface.
Do electric lines exist?
Electric field lines never intersect. … The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential. If the electric field in a given region of space is zero, electric field lines do not exist.
Do the electric line of force really exist what is about the electric field they represent?
Electric lines of force are drawn to point out the direction of electric field. They originate from positive charge and terminate at negative charge. … Electric lines of force represents the direction of electric field.
Are electric lines of force imaginary?
An electric line of force is an imaginary curve drawn in such a way that tangent to this curve at any point gives the direction of the electric field at that point. It can be a path with maybe a curve or a straight line.
Can electric field lines end at infinity?
Electric field lines either originate on positive charges or come in from infinity, and either terminate on negative charges or extend out to infinity. The number of field lines originating or terminating at a charge is proportional to the magnitude of that charge.
Why can electric field lines never cross?
Electric field lines cannot cross. … This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
What direction do electric field lines travel?
These pattern of lines, sometimes referred to as electric field lines, point in the direction that a positive test charge would accelerate if placed upon the line. As such, the lines are directed away from positively charged source charges and toward negatively charged source charges.
Does magnetic field lines really exist?
No, a magnetic field is not a discrete bunch of lines. … Field lines are real in the same sense that the arrows are, or the contour lines on a map. They aren’t just a picture – they genuinely represent something mathematical about the field.
Do field lines and electric fields actually exist?
Do field lines and electric fields actually exist? … electric fields do, but field lines do not. Field lines provide a model of an electric field but electric fields provide a method of calculating the force on a charged body.
Are fields real?
“The fact that the electromagnetic field can possess momentum and energy makes it very real … a particle makes a field, and a field acts on another particle, and the field has such familiar properties as energy content and momentum, just as particles can have.” In practice, the strength of most fields diminishes with …
