What is an equipotential surface a uniform electric field?

For an isolated point charge, the equipotential surface is a sphere. i.e. concentric spheres around the point charge are different equipotential surfaces. In a uniform electric field, any plane normal to the field direction is an equipotential surface.

How are electric field lines represented?

Since electric field is a vector quantity, it can be represented by a vector arrow. For any given location, the arrows point in the direction of the electric field and their length is proportional to the strength of the electric field at that location.

What is the geometric relationship between electric equipotential lines and electric field lines?

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.

Why do equipotential surfaces due to a uniform electric field?

Answer: The equipotential surfaces due to a uniform electric field not intersect each other because two different equipotential surface have different electric potential, so if they intersect then the point of intersection will have two different potentials at the same point which is not possible.

Which of the following figure represents the electric field lines?

If we have a negative charge, then its electric field lines are radially inward direction as shown in the above figure. Because electric field lines start from infinity where the positive charge is supposed to be existing and end at a negative charge. Thus, option (B) is the correct answer.

What do field line represent?

Since a field line represents the direction of the field at a given point, if two field lines crossed at some point, that would imply that the electric field was pointing in two different directions at a single point.

What is equipotential line?

An equipotential line is a line along which the electric potential is constant. An equipotential surface is a three-dimensional version of equipotential lines. Equipotential lines are always perpendicular to electric field lines.

What is the electric potential at any point on the equatorial line of an electric dipole?

Electric potential at any point in the equatorial plane of dipole is zero.

What is meant by Equi potential surface and draw any two equipotential surfaces in the uniform electric field?

Any surface over which the potential is constant is called an equipotential surface.In other words, the potential difference between any two points on an equipotential surface is zero. Some important properties of equipotential surfaces : 1. Work done in moving a charge over an equipotential surface is zero.

How do you draw an electric field from an equipotential line?

Given the electric field lines, the equipotential lines can be drawn simply by making them perpendicular to the electric field lines. Conversely, given the equipotential lines, as in Figure 3a, the electric field lines can be drawn by making them perpendicular to the equipotentials, as in Figure 3b.

How do you draw electric field lines?

What are equipotentials physics?

Equipotential or isopotential in mathematics and physics refers to a region in space where every point in it is at the same potential. … Thus, an equipotential would contain both points a and b as they have the same potential.

Where do the equipotential lines begin and end explain?

2. 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.

What is streamline and equipotential line?

Streamline: It is an imaginary curve drawn in space such that tangent drawn to it at any point will give the velocity of that fluid particle at a given instant of time. … Equipotential line: A line along which velocity potential function (ϕ) is constant is known as the equipotential line.

How do you draw a equipotential line?

How do the equipotential lines show that the field is stronger near the electrodes?

Thus, equally spaced (in voltage) equipotentials will be closer together (in distance) where the field is stronger, and further apart where the field is weaker.

What is equipotential surface Class 12?

Equipotential surface is a surface where all the points lying on the surface have the same electric potential. This means that a charge will have the same potential energy at every point on the equipotential surface.

Why are the measured equipotentials lines instead of surfaces for this laboratory?

The measured equipotentials are lines instead of surfaces for this laboratory because the paper used forms a plane which represents a slice through a three dimensional surface and that forms lines. … An infinite number of equipotentials exist depending upon how precisely the potential is measured.

How do the equipotentials show that the field is stronger near the electrodes B How do the field lines show the field is stronger near the electrode?

Since the equipotential lines are perpendicular to the electric field, moving a test charge along an equipotential surface requires no work because the electric force is perpendicular to the motion. … Thus, the electric field is strongest where the equipotentials are closest together.

Where is the electric field strongest?

The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest.

Why are the equipotential lines near conductor surfaces parallel to the surface and why perpendicular to the insulator surface mapped?

And the reason why equipotential lines are perpendicular to the surface of the insulator is because since there will be electric field lines inside of it, then the equipotential lines will be parallel to those electric fields, and thus perpendicular to the surface because the insulator has a constant curvature at every …
