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.
A proton has a positive electrical charge and an electron has a negative electrical charge.
The fundamental property of matter that may be identified as positive or negative is electric charge. Positive charges are carried by protons, negative charges by electrons.
The neutrons are the part of the atom that carry no electric charge. They are found in the nucleus. the protons carry a positive charge and the electrons carry a negative 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.
Protons do have positive electrical charge with value 1.6 x 10-19 C. Photons of course don't have electrical charge Positrons are anti particles of electrons and they have same charge as that of proton. Neutrons don't have electrical charge.
The kinds of electric charge are positive charge and negative charge
A negative charge is caused by a excess of electrons and a positive charge by their lack.
A negative point charge will be attracted towards a positive point charge in an electric field.
some is positive and some are negative and some are neutral and thats how there differ
No electric charges may be positive or negative - electrons have a negative charge; ions have a positive charge.
The two types of electric charge are positive and negative. Positive charges repel each other, as do negative charges, while opposite charges attract each other.
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 is one of the two possible electrical charges, the other is ..........? the NEGATIVE charge.
The two types of electric charges are positive and negative. Positive charges repel each other, as do negative charges, while positive and negative charges attract each other.
The strength of the electric field between positive and negative charges is determined by the magnitude of the charges and the distance between them. The direction of the electric field is from the positive charge to the negative charge.
In the electric charge.
A proton has a positive electrical charge and an electron has a negative electrical charge.
