Abstract
<p class="1Body">What is “electronic charge”? Why there are two kinds of charges? Why do the same charges repel, and dissimilar charges attract each other? Why does their behavior agree with Coulomb's Law? These are among the most basic questions of physics. Let us assume the existence of a kind of microparticle in the universe, which we can call an electon for our purposes here. Three situations are possible: if an object contains a surplus of electons, it will be positively charged; if a deficit of electons, it will be negatively charged; if an object contains electons equal to its expected value, in the saturated state, it is neutral. The charged objects, containing these electons, have the ability to exchange charged or uncharged microparticles in order to achieve a neutral state. The acting force between two charged objects comes from the exchange of charged and uncharged microparticles. The same charges repel, and dissimilar charges attract each other. The value of force is consistent with Coulomb's Law. The material homogeneous between two charged objects affects the value of the acting force between them, but does not affect the direction.</p>

If an object contains more electons than expected, it is in a surplus state, and positively charged; if an object contains fewer electons than expected, it is in a scant state, and negatively charged; if an object contains electons equal to its expected value, it is in a saturated state, and is neutral
Summary
Humans observed the phenomenon of electricity, and recognized that there are only three options: positive, negative and neutral. A particle is considered to have a charge if it carries either positive or negative electricity. The quantity of electricity in charge is called charge quantity. In 1785, Coulomb (CA Coulomb, 1736-1806) derived Coulomb's Law of electrostatic interaction through torsion balance experiments (Cheng & Jiang, 1978). 1731-1810) discovered a law which was more accurate (Cheng & Jiang, 1978), but the result has not been recognized. First, the nature of the charge is discussed, and the charge interaction principle and Coulomb’s Law are researched
