Do electric field lines radiate outward like spokes on a wheel?

Do electric fields point outward or inward?

We define the "direction"of an electric field to be the direction of the force it exerts on a positive test charge placed in the field. So if there is some charge inside a shell, the field outside the shell points outward if the charge inside is positive, and inward if the charge inside is negative.

This exerts a force on anything that has an electrical charge?

An electric field has what are called lines of force that radiate outward from the electric charge that creates them. It is the "touch" or the interaction with these lines of force that allow an electric field to exert a force (an electrostatic force) on anything with an electric charge.A fundamental law of electrostatics is that like charges repel and opposite charges attract. A charge will have an electric field around it, and if another charge is nearby, the fields of the charges will interact. Like charges will "push" on each other, while opposite charges will "pull" on each other. It's the fields of the respective charges that interact to cause the effects we see.All electric charges have associated electric fields around them. It is possible to "see" the electric fields like we "see" gravimetric fields. Both forces can "reach across" space to interact with objects at a distance from the source of the force. The field lines (lines of force) carry the force outward and are the means by which interaction occurs.

How is the strength of an electric field indicated with electric field lines?

Given a positive charge the electric field lines are drawn starting from the charge and pointing radially outward, ending in principle at infinity, according to the electric field strength being proportional to the inverse square of distance. From the definition of electric field we know that the modulous of the electric field is greater for smaller distances from the field generating charge. Since the electric field lines point radially outward we consider the density of lines an indication of the strength of the electirc field. If we immagine to trace a circle around the electric field generating charge, of radius slightly greater than the radius of the object which holds the charge and therefore generates the electric field, such circle will be crossed by a number 'n' of lines. The density of lines crossing the cirle will then be the circumference of the circle divided by the number 'n' of lines. For a larger circle we will have a greater circumference, but same number of lines 'n', and therefore a smaller density of lines crossing it, which idicates a lower intesity of electric field for a greater distance from the charge.

In which direction does the electric field point at position directly east of a positive charge?

Yes. The electric field in physics is represented by a vector, it has three components governing the field strength in the up-down, left-right and forward-backwards directions.

Electric field is positive or negative?

Did you mean "The strength of electric field is positive or negative"? Anyway, there is your answer.. The strength of an electric field E at any point is defined as the electric force F exerted per unit positive electric charge q at that point, or E = F/q.You can say that it is positive.

What is the Difference between line charge density and surface charge density?

The electric field of an infinite line charge with a uniform linear charge density can be obtained by a using Gauss' law. Considering a Gaussian surface in the form of a cylinder at radius r, the electric field has the same magnitude at every point of the cylinder and is directed outward. The electric flux is then just the electric field times the area of the cylinder.

What is meant by electric field intencity?

An electric field can be represented diagrammatically as a set of lines with arrows on, called electric field-lines, which fill space. Electric field-lines are drawn according to the following rules: The direction of the electric field is everywhere tangent to the field-lines, in the sense of the arrows on the lines. The magnitude of the field is proportional to the number of field-lines per unit area passing through a small surface normal to the lines. Thus, field-lines determine the magnitude, as well as the direction, of the electric field. In particular, the field is strong at points where the field-lines are closely spaced, and weak at points where they are far apart. Electric Field intensity It was stated that the electric field concept arose in an effort to explain action-at-a-distance forces. All charged objects create an electric field which extends outward into the space which surrounds it. The charge alters that space, causing any other charged object that enters the space to be affected by this field. The strength of the electric field is dependent upon how charged the object creating the field is and upon the distance of separation from the charged object. In this section of Lesson 4, we will investigate electric field from a numerical viewpoint - the electric field strength.

Why does the electric field inside a dielectric decrease when it is placed in an external electric field?

The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.

What are the following correctly describe electric field lines?

If we place a charged body to a position it feel a force which depends the presence of other charged body around it. Now we can say something was there in that position before placing that charged body. Here arise a concept of electric field.Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge. A simple isolated electron in an earth can create an electric field in the moon eventhough its negligible.

Which of the following are created by an arrangement of electric charge or a current?

Can an electric field exist without a magnetic field?

An electric field can exist even without the presence of a magnetic field. An example of this is a stationary electric field.
