In this PHYSICAL video we will explain the "Explanation of Coulomb's Law".

Today we are going to delve a little deeper into the electric field. To do this we are going to study the electric force. Before we are going to remember about the electric charge. We had seen that when we have two charges of the same sign, when we put them together they repel each other. But when they are of opposite signs (+ and -) when we put them together, they attract. This repulsion or attraction it's not by magic. There is something there that makes it impossible to put the loads together or, on the contrary, help us to put them together. For this we must understand that it exists as a force that what it does is repel when the charges are equal or attract when the charges are different.

Coulomb investigated on the subject and introduced us to Coulomb's Law with the electric force and explained how it was. It tells us that the electric force F is proportional to the charges that we are putting together and inversely proportional to the distance between them. All this force does not happen, for example, if we have two particles of a rotated shape or with any

randomness that we can imagine. It is very simple, this force acts between the charges in a radial way. That is, a line between them and the force acts on this line that separates the two charges. Therefore the force is a radial vector between the two charges.
