Yes.

Work is force times distance, or technically the dot product of vector force times vector distance. Electric fields exert force on charge and the force does work when the charge moves in the direction of the electric force. (In the converse, when the movement of charge is against the direction of force, work is transformed into stored electromagnetic energy.)

Technically, it is the electric field that does work and not the field line.

Mother nature produces electric fields, but humans can not see electric fields. Humans invented the idea of field lines to create a mental picture of the field. The two most common ways are to draw lines in space or to draw a collection of arrows in space.

Note:

One should not confuse this answer with the question of whether work can be done by a magnetic field. A magnetic field can not do work because the direction of the magnetic force is always perpendicular to the direction of motion of charge and hence the dot product of force and distance moved is always zero.

What is Equipotential lines in electric field?

Equipotential lines in an electric field are imaginary lines that connect points having the same electric potential. Along these lines, no work is required to move a charge between the points, as the electric potential is the same. Equipotential lines are always perpendicular to electric field lines.


What do lines represent in an electirc field diagram?

The lines in each diagram represent an electric field. The stronger the field, the close together the lines are.


How is the direction of an electric field indicate with electrical fields lines?

The direction of an electric field is indicated by the direction in which the electric field lines point. Electric field lines point away from positive charges and towards negative charges. The closer the field lines are together, the stronger the electric field in that region.


How closely packed the electric field lines are indicates the strength of the electric field?

true


Which is true of magnetic field lines but not electric firld lines apex?

Magnetic field lines always form closed loops, while electric field lines begin and end on charges. Additionally, magnetic field lines do not originate from monopoles, while electric field lines can begin and end on electric charges.


What do lines represent in an electric field diagram?

The lines in each diagram represent an electric field. The stronger the field, the close together the lines are.


What do you draw to show a stronger electric field?

You can draw electric field lines closer together to show a stronger electric field. The density of the lines represents the intensity of the field - the closer the lines, the stronger the field.


Why electric field lines cannot have sudden brakes in between them?

Electric field lines represent the direction of the electric field at any point in space. If there were sudden breaks in the field lines, it would imply sudden changes in the electric field strength, which is not physically possible. The electric field must vary continuously and smoothly in space.


What is the significance of the number of lines per unit area or density of the electric field lines?

The density of electric field lines represents the strength of the electric field in a given region. A higher density of electric field lines indicates a stronger electric field, whereas a lower density indicates a weaker field. This provides a visual representation of how the electric field intensity varies in space.


What are three facts about electric field lines?

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.


How are magnetic field lines like electric field lines?

Magnetic field lines are similar to electric field lines in that they both represent the direction and strength of the field at various points in space. Both types of field lines are used to visualize the field's behavior and provide insights into the field's properties. However, magnetic field lines form closed loops, while electric field lines start and end on charges.


Can two electric field lines be drawn at a point?

No, two electric field lines cannot originate from the same point because the electric field direction at that point would be ambiguous. Electric field lines always point in the direction of the electric field at a given point and represent the direction a positive test charge would move in that field.
