Ok this is what you did wrong: ||v1||² = v1* . v1 = (1, i, 0)*. (1, i, 0) = 1+(-i)(i)=1+1=2

I do not think so! because they are non conducting spheres... so we can not ignore the effect of the second sphere, I guess! i will look it up more though...

It looks fine to me! ;)

OK,... i hope this be helpful before your quiz! the point is the B field is North-South but the wire is East-West... so take a paper as your horizon and draw a line on it as your wire in East-West. now take your pencil and push it trough the middle od the line and hold it 75 degree North...

No... if you have the Griffiths book please look at page 80. There is a very important discussion in there where students mostly pass reading it very fast! Due to the argue in the last past of page 80, you can not choose the infinity as your potential reference point. you can choose it is a...

i need that solution set tooo!

Wahoo, it looks like i have to answer all my questions alone! if so...! i found the answer! this question is not to calculate the energy but to take the energy levels from the NIST table and plot the, the point is for larger n... the splitting energy gets smaller and smaller almost zero and that...
