I was doing some rotation problems the other day out of my physics textbook when I realized that invariably all the problems dealt with rotation about fixed point (levers and pendulums and such). So I imagined a case in which I had a bar with a certain mass and dimension floating in space and I...
Ah, so the radial static electric field still does exist! I should find this out for myself, but can you give me the relevant equations or a link to a site expressing them? I find it very interesting that the magnitude of the force "felt" should be different for a static field as opposed to an...
So that's the way it simply is. Somehow that's not a very satisfying answer. So be it, but I have a quick follow-up: So if I had some oscillating charges, and some distance away I had some other charged particles, would there no longer be an attractive force pulling them together or pushing them...
I'm have some conceptual problems with electric fields and waves. When I think of electromagnetic waves I imagine field lines emanating from a charge that is oscillating, consequently causing the field lines to oscillate. In diagrams showing field lines, the electric field runs parallel with the...
