Exercise_C_01
We consider a red giant star. The energy is produced by hydrogen fusion in a shell
and by helium fusion in the core.
We assume that the mean density in the hydrogen shell source is 30 g/cm3 and that
the mean chemical composition is X=0.35, Y=0.63 and Z=0.02.
The mean density in the...
of coures how could i forget this! great thanks alot. So i actually just need to integrate phi which goes from 0 to 2pi. but what about my r2 in the vector potiential dipole, i would need to rewrite that one in terms og θ, right?
Im pretty weak in vektors for det plan, cylendrical and spherical coordinat systems, but i can see you suggest the plan coordinat system. Well i gave it a try in the sperical coordinate system, i have attached a image of my attempt, but now i don't know what bounderies i should integrate over to...
Yes pretty sure i should use this equation for the question and yes i forgot the arrow on r.
I don't understand "So what is needed to rewrite this in the coordinate system of your exercise (which was already chosen for you, so you don't have to worry about that any more!) ?"
and thank you...
Hi Guys
I have hards time doing a question in electrodynamics, i have uploaded the problem and i can't figure out how to do question a), i have hard time understanding what coordinat system i should use, cartesien og cylendrical. I have tryed to draw the field lines, its a bit messy, but its...
