Alright guys, I went to the professor and got som help. For posterity in that class (I'm talking to you GC), I am posting the solution. Using a bar chart, we find that we have zero initial energy. That is 0 = KE - Uq .5Iω^2 - pE where p =qs Given p = 2x10^-9 and "s" = .1m, then p =...

Homework Statement An electric dipole consists of 1.0 g spheres charged to +(-) 2.0 nC at the ends of a 10-cm-long massless rod. The dipole rotates on a frictionless pivot at it's center. The dipole is held perpendicular to a uniform electric field with field strength 1000 V/m, then released...

HAHA yes. I've checked my answer to the point of insanity and I am willing to bet that the book once again had a typo. Anyways, good luck with the last two. See you in class on Monday. -Oscar

Hi all, I am having the same exact problem... As a matter of fact, I think that we may be in the same physics class. Hehe. Parts A,B, and C agree with OP and the back of the textbook. However, I cannot get part D to match. According to the book, the answer is 1.5kNm yet mine continues to come...
