If the given point charge is of positive one then the field points away from the charge. This is because we define the field at a point as the FORCE acting on unit POSITIVE charge. Like charges have to repel and hence the direction.
If, other wise, the point charge is negative then electric field due to this negative charge would be towards the negative and not away from it.
What else can I help you with?
When determining an electric field must a positive test charge be used or would a negative one do as well?
Either a positive or a negative test charge can be used to determine an electric field. The direction of the electric field will be defined by the force experienced by the test charge, with the positive test charge moving in the direction of the field and the negative test charge moving opposite to the field.
Is it possible to have zero electric field value between a negative and positive charges along the line joining the two charges?
Yes, it is possible to have zero electric field values at certain points between a negative and positive charge, depending on the distances and magnitudes of the charges. If the magnitudes of the charges are equal and the distances are adjusted accordingly, the electric fields may cancel each other out at specific points along the line joining the charges.
What is true about an object pulled inward in an electric field does it have negative charge object has charge of different field object has neutral charge or object has a charge same field?
An object being pulled inward in an electric field typically implies the object has a positive charge, as oppositely charged objects are attracted to each other. If the object has a negative charge, it would be pushed away from the field. If the object has a neutral charge, it would not experience any force in the field.
Where is the electric field strong and weak?
The electric field is strongest close to the source charge and weakens with distance from the source. It is weaker in regions with insulating materials compared to regions with conducting materials. Additionally, the electric field is weaker inside a conductor compared to outside the conductor due to charge redistribution.
Electric field of a proton?
The electric field of a proton is a force field that exerts a force on other charged particles in its vicinity. It is generated by the electric charge of the proton, which is positive. The strength of the electric field decreases with distance from the proton according to an inverse square law.
What is the direction of the electric field near a negative charge?
The electric field near a negative charge points radially inward towards the charge.
How do you compare and contrast the electrical field around a negative charge and the electric field around a positive charge?
The electric field around a negative charge points inward, towards the charge, while the electric field around a positive charge points outward, away from the charge. The electric field strength decreases with distance from both charges, following an inverse square law relationship.
What direction does the electric field point at a position directly east of a negative charge?
The electric field points toward the negative charge.
What is the electric field due to a line of charge?
The electric field due to a line of charge is a vector field that points radially outward from the line of charge. Its magnitude decreases as the distance from the line of charge increases.
If the electric field due to the excess charge on the Earth points downward what type of charge does the Earth carry?
The Earth carries a negative charge, as the electric field due to excess negative charge on the Earth points downward.
What is true about an electric field around a negative charge?
The electric field around a negative charge points radially inward towards the charge. The field lines move from areas of higher potential to lower potential. The magnitude of the electric field decreases with distance from the negative charge.
What determines the number originating from a charge when an electric line is drawn?
The number that originates from a charge when an electric field line is drawn represents the magnitude of the charge creating the field. The field lines help us visualize the direction of the electric field and the relative strength of the field at different points around the charge. The closer the field lines are together, the stronger the electric field.
Can you find a point where the electric field is zero?
Yes, the electric field can be zero at points where the net charge is zero or where the electric field vectors cancel each other out.
In which direction does the electric field point at a position directly north of a positive charge?
The electric field points directly away from a positive charge. Therefore, at a position directly north of a positive charge, the electric field would also point directly away from the positive charge.
The direction of the electric field tells you what?
The direction of the electric field tells you the direction a positive test charge placed in that field would experience a force. If the field points away from a charge, a positive test charge would repel from it, and if it points towards a charge, the test charge would be attracted to it.
In which direction does the electric field point at a position direcly south of a positive charge?
The electric field points away from a positive charge in all directions, meaning it would also point away to the south of the charge.
What is true about an electric field around a positive charge?
It will be directed away from the positive charge. It will attract any other negative charge and repel any positive charge. Its magnitude is given by E= KQ/R where K = 9x 109 C2m-2N-1 Q is the charge producing field R is the point where electric field is to be calculated
