AI Thread Summary
Like charges repel each other while unlike charges attract due to fundamental principles of electromagnetism. The interaction between charges is governed by the product of their magnitudes, leading to repulsion or attraction based on their types. When like charges come close, their overlapping fields increase energy storage, resulting in repulsion to minimize energy. Conversely, overlapping unlike charges result in a cancellation of fields, releasing energy as light. This phenomenon is rooted in established theories such as the Standard Model and quantum field theory.

why like charges repel n unlike charge attract each other?
 
Physics news on Phys.org
What sort of answer do you want?
The empirical one (people have always observed that it is so), the electrodynamical answer (the force law between charges depends on the product q_1 q_2), the field theoretical one or the standard-model argument?

My point it, is seems to be such a basic fact of nature that you can get as fundamental as you want.
 
it moves toward the state of minimum energy.
 
why its a fact i want to knw that ?
 
can u please explain how they move towards state of min energy?
 
i can explain why its the state of minimum energy.

the energy in each infinitesimal part of the field is proportional to the square of the field intensity. when 2 like charges overlap then their fields are everywhere doubled. hence four times the energy of a single particle is stored. when they repel apart that leaves half the energy to be released as kinetic energy.
 
tis shows y like repel each other wat abt unlike charges?
 
same thing. the field of 2 overlapping unlike charges is zero. all the energy is released as light.
 
thanks

but can u provide me link of tis if u knw(multimedia)

i can't get u completely

Yes, so did a lot of other people. This has led to the development of theories like the Standard model, QFT and string theory :smile:

because they are extremely heterosexual and homophobic.
