which approach would you recommend ? to use on this one? circles? by the way thank you for your help so far :)

sorry i guess i took a wrong turn on this one but magnetic field of a moving charge would then be B=(μ_o/4∏)*(qv x \hat{r})/r^2 ?? and to simplify integration of a sphere consider it a circle? 0 to pie?

so then the magnetic moment of each charge would be usable? μ=Q/(2Mass)*\alpha

Hello tiny time :) and thanks for clarifying the non conducting part ;) Well to be honest i don't know where to start i know i can find the e field by placing it inside a gaussian surface (bigger sphere) but that is really all i have which isn't really the scope of this problem i think ?

A NONCONDUCTING sphere with uniform volume charge density ? HELP! Homework Statement so this is the problem, a nonconducting sphere of radius \alpha has a uniform volume charge density with total charge Q. the sphere rotates about an axis through its center with constant angular velocity...

thanks guys just hammered through it think i got my head around it :)

well one of my issues atm that forgot to add on there is the first term is over zero isn't it? due to the lower bounds and the serious should be 1-1/2x^2 +1/24x^4... if that helps you find where i am lost :)

well i was seeing that (2+x^2) has no discontinuity so shouldn't the radius be infinity?

integrate from 0 -> 1 (1-cosx)/x dx find maclorein approximation this has been killing me any ideas??

quick help on this i seem to be missing some logic or process determine the lower bound the radius of convergence of series solutions about the given X0 (2+x^2)y''-xy'+4y=0 xo=0

tried this guess but yield wrong answer guess ill do a few more times thanks all

i solved homogenous but y"+y'+4y = 2sinh(T) is giving me trouble also have a hint sinh t = (e^t - e^-t)/2 also my "guess" was aE^t +Be^-t=Y maybe my guess was wrong?

sorry about that folks had a brain fart was using nf instead of H :)

Homework Statement An L-C circuit has an inductance of 0.430 and a capacitance of 0.240 . During the current oscillations, the maximum current in the inductor is 1.40 . What is the maximum energy stored in the capacitor at any time during the current oscillations? Express your answer in...

ur amazing thank you ^-^
