I want to know what is the source of electron and proton get thier charge ?
I believe charge is a fundamental property of particles and has no underlying explanation.
Why fundamental question have no answers.
It has to be?
No matter what answer we give you, there will always be another "Why?" question behind it, until finally we get to "Because that's how the universe we live in behaves".
Why do objects fall at 9.8 m/sec^2 on the surface of the earth? Because of gravity - Newton's law says ##F=Gmm_E/r^2##. Why is that Newton's law and not something else? Well, because that's how the universe we live in behaves. Why does the universe we live in behave that way? Physics and other experimental sciences can't answer that question, all they can do is tell us how the universe behaves.
