Want this question answered?
A proton has a positive electrical charge and an electron has a negative electrical charge.
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.
We could just as well use a negative test charge to determine an electric field, but then the Electric field vector would point opposite the direction of the force on the test charge.
Since there is charge separation in a polar covalent bond, there is also resultant electric field from partial positive charge to partial negative charge.hence due to electric field in one direction and also magnitude of equal and opposite charge.....it is a vector.
electric charge
Electric Field between positive and negative charges. If the Electric Field in which both the positive and negative charges are present is stronger than the Electric Field between the two charges we are talking about, the the negative charge will move away from the positive charge in that positive direction of the field. If not, then the negative charge will get attracted to the positive charge and stay at the position of the positive charge. It will be pulled toward the source of the electric field. (Novanet)
Positive charge and negative charge
The kinds of electric charge are positive charge and negative charge
Electric charge comes in two types, called positive and negative.
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.
some is positive and some are negative and some are neutral and thats how there differ
A negative charge is caused by a excess of electrons and a positive charge by their lack.
No electric charges may be positive or negative - electrons have a negative charge; ions have a positive charge.
Positive charge is one of the two possible electrical charges, the other is ..........? the NEGATIVE charge.
A proton has a positive electrical charge and an electron has a negative electrical charge.
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.

The direction of the flow of electric current. In a positive object, electrons flow to it because it has an abscence of negative charge (aka electrons). In a negative object, it has an abundance of negative charge (electrons) so electrons flow away from it.
