@phyzguy : Thanks for your suggestion. I just read that. I never thought there could be a whole section there discussing this topic! By the way, I find Feynman's lectures in general a bit complicated as a first time learner. At this point of my study, I think I would just leave the question (for...

That's what I am actually confused about. I don't understand what does Purcell mean by these lines: "What holds the electron together is as mysterious as what fixes the precise value of its charge. Something more than electrical forces must be involved, for the electrostatic forces between...

Thanks to both of you. I understand it now.

I was reading the book "Electricity and Magnetism" 3rd edition (Purcell, Morin) and under section 1.3 the book says (I quote): "What holds the electron together is as mysterious as what fixes the precise value of its charge. Something more than electrical forces must be involved, for the...

Thank you for your answer. Please help me a bit more. So if two charges along with an observer (let's call him / her "X") is moving at a constant velocity and another observer ("Y") is not moving; then "X" can apply Coulomb's law but "Y" can not - am I correct?

Hello. I am an intro Physics student and this is my first post here. In Coulomb's law the charges are said to be stationary. I need some clarification about what does it mean for two charges to be stationary: A. Does it mean that the charges are not moving with respect to each other? (But...
