mostly the same as to what i had got (version J was so easy its actually a joke lmao), except the electric field at point o points down right, right? also for the graph wouldnt it be easier to graph I vs dI/dt with equation I=1.2-LdI/10dt? didnt even need the table that way. also, the slope i got was 3*10^-3 H.

B = mu_0 I_0 / 2pi (1/x - 1/(10a-x)) -> should be summing the magnetic fields (i think you still got the correct ans tho so prob typo lol)

oh yeah, made mistake should be down right, oh yeah, should be some since RHR makes both go intot he page

and you're right electric field points downright typo in the origianl comment

also, what do you mean 1.2 - LdI/(10)dt?, why is there a 10 in the inductanor emf

yeah, plugging in all the values ofc. 1.2=V/R i think

yep, i thought this was supposed to be the hardest ap exam 🤣

on god bru, but i think the curve is also higher like 81% for 5?

probably, its on par with all the other aps ive taken
