simple question no answer?no wiki? no thought? no opinion?must be a dumb question. how do you think Box?
suppose we can measure the force between 2 electrons light year apart, can we assume electron has a light year radius?
what if we can measure any amount of force? is force liner?
Quote from: jcccsuppose we can measure the force between 2 electrons light year apart, can we assume electron has a light year radius?No. Of course not. What led you to such a crazy notion? First of all the electron has zero radius. The force exerted by one electron by another is determined solely by the distance between them (since the charge on an electron is a fixed and given quantity).Quote from: jcccwhat if we can measure any amount of force? is force liner? No. Most forces aren't linear. (once again you have yet another spelling error. It's "linear" not "liner").
if electron has zero radius, it should not occupy space, how could a photon hit an electron?
the distance between charged particles is linear, f=ke x q1q2/r^2, therefore force is linear?
Quote from: jcccif electron has zero radius, it should not occupy space, how could a photon hit an electron?I did some digging and found the answer. As I said, you keep thinking in terms of classical particles whereas photons and electrons are quantum mechanical particles so the impressions like this that you use are totally wrong. The answer lies in what's known as a scattering cross section. The Klein–Nishina formula gives the differential cross section of photons scattered from a single free electron in lowest order of quantum electrodynamics. A differential cross section is a scalar that only quantifies the intrinsic rate of an event.You can read more about these things at:...sorry, you cannot view external links. To see them, please
REGISTER or LOGINAfter all this time that we've all suggested reading a book on physics have you ever seriously considered following those suggestions even a little bit?
Pete. Seriously? You expect jccc to ever understand what you are asking him to read? I admire your perseverance.
First of all the electron has zero radius.
Ummm....well.....the classical model is a point charge but we know the electron has mass, angular momentum, and a magnetic moment, so we can define something analogous to a radius even though the classical equations give us the wrong answer.
is this science or politic?
how electron and proton contact?
is electron circling or not?
how can 1 electron circling 1 proton to form 3 d hydrogen atom? isn't orbits are 2 d?
why is micro world is so strange? because we can not see it clear?
isn't in micro world, newton's law not working? coulomb's law not working?

Simple fact: if you put something in water it gets wet.Simple question: if you put an electron in water does it get wet?Ponder this a while and then think about your other questions in the same way. I will give hints if you (jccc) ask for them.
