When determining an electric field must a positive test charge be used or would a negative one do as well?

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.

What is proton electric 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
Protons have no electric charge?
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.
Is an electric charge a property of just electricity or is charge a property of all atoms?
Atoms contain both positive (protons) and negative (electrons) electric charges. But in the vast majority of atoms these positive and negative electric charges balance, canceling and resulting in zero total electric charge. When electrons detach from atoms we generate electricity. Where there are fewer electrons there is a positive charge. Where there are more electrons there is a negative charge. When two places have different charges we get an electric voltage. When electrons flow from a negatively charged place to a positively charged place we get an electric current.
What is the charge of anion?
A cation has a positive charge and an anion has a negative charge.
What are the 2 types of electric charges?
Positive charge and negative charge
What are the kinds of electric charge?
The kinds of electric charge are positive charge and negative charge
What are two types of electric charge?
Electric charge comes in two types, called positive and negative.
Does current electricity have positive and negative charges?
No electric charges may be positive or negative - electrons have a negative charge; ions have a positive charge.
Compare and contrast The Electric Field Around The Negative Charge And The Electric Field Around A Positive Charge?
A negative charge is caused by a excess of electrons and a positive charge by their lack.
How do the particles of an atom differ in electric charge?
some is positive and some are negative and some are neutral and thats how there differ
A negatively charged object is placed within a positive electric field. what happens to the object?
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)
What electric charge can either be positive or negative?
Positive charge is one of the two possible electrical charges, the other is ..........? the NEGATIVE charge.
What is proton electric charge?
A proton has a positive electrical charge and an electron has a negative electrical charge.
What charge does amber get when rubbed with nylon?
Nylon - positive chargeAmber - negative charge
How does a negative differ from a positive ion?
In the electric charge.
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.
