We always use them to solve physics problems, so it is easy to take them for granted. But why I am Are there such numbers in nature and why do they only have those specific values? Because, listen, if they were only slightly different, the universe could be unable to support life. Have any cosmic watches set these parameters? Isaac Newton thought so.
One of the most basic of these numbers is the electric constant, k. It is a value that allows us to calculate the forces between electric charges. This is a big problem if we consider that all the subject is made of only three things: electri, neutrons and protons, two of which have an electric charge. The interaction between electrons is what forms molecules to create you and everything around you. Otherwise it would be all just an undifferentiated soup.
But how do we know the value of the electric constant? Also, what does it have to do with other fundamental constants? And after all, it’s true Truly fundamental? We investigate.
The law of Coulomb and constant
When we say that something has an electric charge, we mean that it has a different number of protons and electrons. If the dryer removes some electrons from the socks, they are positively loaded. If they earn electrons, they will be negatively loaded. (Note: you cannot remove the protons, since I am in the core of the atom. It would imply a nuclear reaction, which nobody wants.)
If you have two objects with opposite accusations, they attract. If they have the same charge, they repel each other. Here is a demo you can do alone: take a piece of transparent tape and put it on a smooth table. So put a second piece above that and pull them together. Now, if you separate them, one will be positive and one will be negative; Keep them in the vicinity and they will fold each other.
If you repeat the process, you will have two positive and two negative ribbons. Keep two with similar charges close to each other and you will see that they repel each other, as in the photo below:
