Finished high school, no college (19). I was studying Coloumb's law, electric flux and so on, and i stumbled upon that formula. Just wanted to know why the formula valid. That link, with gauss law, it may help me prove myself, just need to crunch the numbers.

Yeah, sorry, one plate comes with sigma/2epsilon0, another comes with sigma/2epsilon0, add them together and we get sigma/epsilon0. Anyone wants to share why is the electric field sigma/2epsilon0?

You can try on youtube, khan academy, easy to learn!

Why electric field between 2 charged plates is sigma(surface charge density)/(2epsilonO) permitivity of free space?

Good to know there are supporting people around here. Thanks frandango!

Well, i like running. I would just want some explanations about those things(that bohr model). Can't a guy from here post some kind of "qm in 3 easy steps" or "Qm for noobs in 10 minutes" video clip on youtube? main thing, i am interested on why electrons spin around the nucleus. what is...

I chose the helium because inside hidrogen, the repulsion force between electrons don't exist. Ok, someone here can explain this trowing some quantum physics terms. Don't forget, act as i am a chimpanzee and i understand only simple things. Thanks!

Already tried that, but somehow, wikipedia thinks that only scientists are reading that. Of some reason, my brain can't read those symbols, many times confusing me more. I guess here is someone that can explain this things for monkeys too.

Yeah, i guess so. So, it's called Bor model, good to know.

Hello! Anyone out there that can explain the helium model? Movement of electrons, forces, speed, etc? In an non excited atom.

well, dipole have 2 charges equal but opposite. if i am far away, and i am a proton, i feel the force of a charge pushing me with a force equal x, but i also feel a force attracting me also of x magnitude. but the dipole's formula states that i should feel q1 x q2 x k divided by distance cubed...

Hy, i am back with my annoying questions about this and that. Could everyone tell me why the frigging dipole have an electric field that drops with 1/r^3? i mean, if i am far away , i should feel no electric field, you know, q2 = -q1 , so they cancel, but i feel (q1 q2 k)/r^3.What the HECK?

well, i know, i was just predicting my future, in case i mechanically learn the formulas, not knowing the principle it works. I may forgot them, or scramble the terms involved. Others who gave a reply on post, thank you, you helped me to understand better the Schrödinger equation proof. Phase...

Hy folks! I am new in here.Anyone can give a basic intuition about why the acceleration formula actually works? I mean, my brain is not capable to "nerd-ize" formulas, i either forgot them , i either on a test write the coulomb formula something like (q1 q2 r^2)/2pi eps0. I am shure if i...
