Why the same charges forces opposite


soap bubble

Recommended Posts

Why the same charges forces opposite,differet ones forces each other...

I know the the (-) charges mean having electron and (+) mean absence of electron but still I cannot explain where this forces come from???

 

Is the a reason of max. irregularity min. energy?

or

Is there any importants efects of photons??

or as anybody says,

 

To explain this should I know The Theory of Quantum Electrodynamic?

Biological analogy:

if two women (or two men) would feel attraction,

any specie would disappear in the first generation.

Nothing would exist if it would be reverse, in physics, and biology.
Proton would attract other proton, and so on, and very shortly we would have Universe in one point.

Where the electrostatic force comes from? From nowhere if you consider it to be fundamental. That's linguistics or logic more than physics.

 

Now one (several) more general theory exists that unifies electric and magnetic forces with the weak force and possibly the strong force, but it won't give you the sort of explanation you seek, probably... Just like electromagnetism, they tell how to compute a force, and nothing more.

 

So you'll get no better answer than a formula. No tiny springs between the particles, no streams flowing between... Because this force is fundamental: it explains other things and is not explained by others.

 

Think of taste: bacon tastes salty (and more), but how does salt taste? Just, well, salty - because it's a fundamental flavour.

Why do charges of same sign repel an other? That's observation. It does not result from a theory. The theory is elaborated to fit the observation.

Yes. QED is needed to explain the interactions between electrons. Somehow a photon is exchanged when two electrons collide and that causes them to repel each other.

Note: the last line. Ever heard of displacement current in maxwell's correction for Ampere's circuit law? Hertz proved it's real 8 years after the formulation of that theory. Science works either ways.
