The equipotential lines became more oval shaped near the charge with more than one. The lines near the center also were more curved towards the double charge. When the dipole was two charges of the same type it was more or less the same but the radius of the circles was larger.
What is the relationship between electric field lines and equipotential lines that you observed in doing the lab?
Electric field lines begin on positive charges and radiate away from them toward negative charges, where they terminate. 3. Equipotential lines are lines connecting points of the same electric potential. All electric field lines cross all equipotential lines perpendicularly.
What is the relationship between equipotential lines and electric field?
Equipotential lines are always perpendicular to the electric field. In three dimensions, the lines form equipotential surfaces. Movement along an equipotential surface requires no work because such movement is always perpendicular to the electric field.
How would the electric field at that point be affected if the charge there were doubled?
(b) How would the electric field at that point be affected if the charge there were doubled? Would the magnitude of the electric force be affected? of the ratio i.e. the electric field would be unchanged.
How does the spacing between the equipotential lines change as you get farther from the charge?
Note that the potential difference (which is more important than the value of the potential at a point) between one equipotential line and the next is a constant value, but the lines get further apart as you move away from the object because the field decreases – the farther you are from the object, the smaller its …
What is the difference between electric field lines and electric field vectors?
Field lines start on positive charges and end on negative charges. The direction of the field line at a point is the direction of the field at that point. … The field vector at any point gives the direction of the field at the point, and the color of the vector shows the strength of the field.
Can we produce an electric field in which the electric field lines are parallel and equally spaced?
In a region of space, I have an electric field represented by parallel curves as shown in the diagram. The curves are equally spaced. We know that a uniform electric field can be represented by lines that are parallel and evenly spaced.
What is the relationship between the direction of the equipotential lines you have drawn?
Equipotential surfaces have equal potentials everywhere on them. For stronger fields, equipotential surfaces are closer to each other! These equipotential surfaces are always perpendicular to the electric field direction, at every point.
What does it mean when equipotential lines are closer together?
Equipotential lines. Equipotential lines provide a quantitative way of viewing the electric potential in two dimensions. Every point on a given line is at the same potential. … When lines are close together, the slope is steep, e.g. a cliff, just as close equipotential lines indicate a strong electric field.
Can electric field lines cross each other?
Electric field lines never cross each other. Electric field lines are most dense around objects with the greatest amount of charge. At locations where electric field lines meet the surface of an object, the lines are perpendicular to the surface.
What is the total electric field created by all three charges together at the center of the equilateral triangle?
The force on unit positive charge at the centre, due to the three equal charges are represented by the three sides of a triangle taken in the same order. Therefore, electric field intensity at centre is zero.
Which of the following is not true about electric field?
Two electric field lines can never cross each other. Electrostatic field lines do not form any closed loops. Electric field lines cannot be taken as continuous curve. In a charge-free region, electric field lines can be taken to be continuous curves without any breaks.
What is electric field equation?
The electric field E is defined to be E=Fq E = F q , where F is the Coulomb or electrostatic force exerted on a small positive test charge q. E has units of N/C. The magnitude of the electric field E created by a point charge Q is E=k|Q|r2 E = k | Q | r 2 , where r is the distance from Q.
What would the electric field lines look like if the electric field was constant?
Related to your specific question, if the electric field is constant, then the slope of the potential is a constant which means that the potential is changing linearly. If the potential is constant, then the slope of the potential is zero, which means the electric field is zero.
Why are the electric field lines normal to the equipotential lines at points of intersection?
Electric field lines are normal to equipotential surfaces because that is the only way no current /emf can be set upon the equipotential surface as the potential difference on equipotential surface is zero.
Why are Equipotentials the same distance apart?
We draw equipotential surfaces that connect points of the same potential, although in two dimensions these surfaces just look like lines. … The difference in potential between neighboring equipotentials is constant, so the equipotentials get further apart as you go further from the charge.
