It’s fun of Think of fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational constant and the planck constant, and they are “fundamental” in the sense that we cannot derive theoretically, we can only measure them.

We use them to solve physics problems all the time, so it is easy to take them for granted. But why are There are such numbers in nature, and why do things simply have these specific values? Because, listen, if they were only slightly different, the universe could be unable to support life. Have some cosmic watchrs defined these parameters? Isaac Newton thought.

One of the most fundamental of these numbers is the electric constant, k. It is a value that allows us to calculate the electrical loads of the Bethaeen forces. It is a big problem when you consider that all the material is made of only three things: electrons, neutrons and protons, two of which have an electrical load. The Bethaeen Electrons interaction is what forms molecules to create you and everything around you. Otherwise, it would only be an undeveloped soup.

But how do we know the value of the electric constant? Also, what has it to do with other fundamental constants? And besides, is it REALLY Fundamental? Let us investigate.

Coulomb’s law and constant

When we say that something has an electrical load, we mean that it has a different number of protons and electrons. If your dryer removes certain electrons from your socks, they become positively loaded. If they gain electrons, they will be negatively loaded. (Notes: you cannot remove the protons because they are in the nucleus of the atom. This would influence the nuclear reaction, that no one wants.)

If you have two objects with opposite loads, they attract. If they have the same charge, they grow back. Here is a demo you can make yourself: Take a piece of adhesive tape and place it on an SMOTH table. Then put a second piece on it and remove them together. Now, if you separate them, we will be positive and a will be negative; Hold them nearby and they will fold towards each other.

If you repeat the process, you will have two positive strips and two negatives. Take two of yourself with costs similar to each other, and you will see that they answer, as in the image below:
