AP Physics C Test

Anyone else have the Phys C test today? I thought it was relatively tough. WTF was up with that charged cloud distribution problem?

Don't ask. After I got my acceptance letter to Berkeley, I found out that this test wouldn't really affect anything. So I didn't really care much for it. I did pretty bad. Oh well.

I took it, but only the Mechanics section. I have never felt so sure of a 5.

I nailed the free response section... Gotta love conservation of energy on that last problem.

hahahah i agree, anyone figure out how to determine that row not thing? I think i did ok on the rest of the test, but that problem was really wierd. I thought mech was pretty easy, but E&M was much harder (both MC and FR)

Berkeley doesn't give credit for AP tests?

hm...all you have to do is use Gauss's law. In part a), since you're outside the cloud, you can just call the whole distribution Q and solve. Part e (? the last one) is slightly harder, as you have to subsitute pV=q in order to solve it. From a), potential difference (voltage) is simply integrating part a). Part b) was an explanation thingy...but I totally forgot what. Part c) was multiplying A by q+ or q- (I forgot what particle was being accelerated) and setting that equal to 1/2mv^2. Forgot what part d) is though..oops.

I didn't think it was too bad. I'm pretty sure I 5-ed the mechanics. Though, I totally blanked out on the last E&M Free Response problem (who would've thought that the plane was moving FORWARD? God I'm a moron), so that wasn't too good...4 or 5 on E&M, I'd say.
