Particle Physics (7 of 41) The Electromagnetic Force

In this video I will explain the electromagnetic force.

Next video in the Particle Physics series can be seen at:

Professor, this is one of my all-time favorite videos that I refer back to. I know that quarks are point particles, but I was wondering if you could pick a distance and do something like this for two up quarks. They could potentially be much closer!🌪

I think when like charges come closer electric flux density b/w them increases. This increase in density pushes the charges away from each other. If we forcibly move out the flux b/w the charges by pushing the charges towards each other the repulsive force will change to attractive force. This attractive force can act at extreamly short distance. As soon as a gap appears b/w like charges, the flux rushes back to fill the gap. Increasing flux density b/w the gap changes attractive force back to repulsive force.

When I supply my house with water, I need to lift 2 six packs of 1.5 lt water bottles (180 N) and it feels quite heavy for each arm (90 N); this is a strong repulsion force for just two protons.
Thank you for sharing.

Misspoke "this number of electrons in this box and this number of electrons in the other box"

You should look, Dr Biezen, at the last video you did on the linear expansion of solids, which I have watched over and over again. There, you calculated a force of over 3, 000, 000 N where the temperature increase was not that much.

I'm just here for the concepts so I can understand electronegativity. I don't like the math, lol.

Correct me if I'm wrong, but doesn't Avogadro's number give you the number of MOLES in a sample?

[soureachsak]

hello, I wonder what would happen if the distance between the protons approach 0? would the electromagnetic force become "infinite"?
In other words, can the distance be 0?
Thank you!

When calculating the charge of each box, why not replace 1.6x10^-19c(charge of one proton) with that same number times Avogadro's number (number of proton's now in box). I didn't understand the whole 1 Coulomb thing, why is it the inverse of 1.6x10^19? Could you help clear these up for me?
