Why do like charges repel and unlike charges attract?

[ankitmohan91]

why like charges repel n unlike charge attract each other?

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.

 

[ankitmohan91]

why its a fact i want to knw that ?

 

[ankitmohan91]

can u please explain how they move towards state of min energy?

 

[granpa]

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.

 

[ankitmohan91]

tis shows y like repel each other wat abt unlike charges?

 

[granpa]

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

 

[granpa]

I'm not aware of any

 

[ankitmohan91]

kkkkk still thanks for the answer

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

because they are extremely heterosexual and homophobic.
