No, they do not exist. Electric field lines are only imaginary. They are the paths along which an imaginary unit charge would move when free. Their number is infinite as paths (Electric field lines) can be infinite.
Do the electric field lines really exist what is about the field they represent?
The electric lines of force that represent the field of a positive electric charge in space consist of a family of straight lines radiating uniformly in all directions from the charge where they originate. A second positive charge placed in the field would travel radially away from the first charge.
Is electric field real or imaginary?
Actually, electric fields are real. Using complex exponentials bears no advantage other than convenient calculation. The interpretation usually is that the imaginary part is discarded and only the real part is taken to be, well, real.
Where do electric field lines exist?
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 is the electric field the strongest?
The field is strongest where the lines are most closely spaced. The electric field lines converge toward charge 1 and away from 2, which means charge 1 is negative and charge 2 is positive.
Where is the electric field the largest?
Electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart.
Is electric field directly proportional to?
For a charge concentrated nearly at a point, the electric field is directly proportional to the amount of charge; it is inversely proportional to the square of the distance radially away from the centre of the source charge and depends also upon the nature of the medium.
Why do we need electric field?
Electric fields (e-fields) are an important tool in understanding how electricity begins and continues to flow. Electric fields describe the pulling or pushing force in a space between charges. … The electric fields of single charges. A negative charge has an inward electric field because it attracts positive charges.
Do electric fields have mass?
It has an electric field. And therefore that field has mass presumably. If I apply a force to that electron, it will accelerate according to F=ma. … The electric field must still exist even when the electron is moving.
How do you know if an electric field is uniform?
If in a particular region of space, intensity of electric field is same (both in magnitude and direction) at each and every point then the electric field in that region is said to be of uniform nature. In other words if electric field vector does not vary with position; it is uniform electric field.
Why can’t electric field lines 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.
Do electric field lines end?
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.
