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.
What else can I help you with?
Which of the following is true about the electric field around an electric charge?
The electric field around an electric charge is a vector field that exerts a force on other charges placed in the field. The strength of the electric field decreases with distance from the charge following the inverse square law. The direction of the electric field is radially outward from a positive charge and radially inward toward a negative charge.
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
What is a radial electric field?
A radial electric field refers to an electric field oriented radially outward or inward from a central point or line. In the context of physics or engineering, it is often used to describe the electric field configuration in certain systems or devices, such as electric motors or charged particles moving along a radial path.
What is electric displacement?
Electric displacement (D) is a concept used in electromagnetism to describe the electric field inside a material. It takes into account the effects of both free and bound charge distributions. It is related to the electric field inside a material through the equation D = εE, where ε is the permittivity of the material and E is the electric field.
What most affect the strength of an electric field?
distance between charged particles.
What factors are involved in electric field?
there are two factors in electric field which are responceable to describe the electric field.that is E and D.

What is the relationship between the electric field and a sphere?
The electric field around a sphere is directly related to the charge distribution on the surface of the sphere. The electric field is stronger closer to the surface of the sphere and weaker further away, following the inverse square law.
Is an electric field?
The electric field is something that exists throughout all space, and only charges can interact with it.The electric field is something used to help describe 'action at a distance'.Imagine two charges separate from each other, both charges experience a force, however they are not touching. The electric field is needed to describe why they experience a force.The electric field strength is defined as the force experienced per charge Q, sitting in that field.E=F/QThe electric flux can be seen much like a flux of water.Here the flux (flow) of water is the amount of water passing through an area.Just as with water, the electric flux is the amount of electric field passing through an area.The stronger the electric field - the higher the flux, per unit area.Imagine flux as a flow of the electric field.Flux = E*A
What is the effect of placing two negative charges in an electric field?
When two negative charges are placed in an electric field, they will repel each other due to their like charges. This repulsion will cause the charges to move away from each other, following the direction of the electric field lines.
What influences the strength of an electric field?
The strength of an electric field is influenced by the magnitude of the charge creating the field and the distance from the charge. The field strength decreases with distance from the charge following the inverse square law. Additionally, the medium through which the field is propagating can also affect its strength.
Why is the electric field is a vector?
Because to completely describe it you must know both how strong it is (magnitude) and in what direction it points.
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.
