Homework 2 results

Just because I know that you are all dying to know ... here is the breakdown for homework 2, average score by question and overall. You'll get your homework back in recitation.
So first: you are really good! The average was 96% overall, very well done on a difficult homework set. Keep it up.

The lower average on #2 does indicate to me that Gauss' law is still tough ... which is understandable. It is hard to get your head around at first, and it is something collectively we need to spend more time on, ideally.

The slightly lower score on question 1 is probably at least in part due to the fact that it was sort of an oddball conceptual question. Once you hear the explanation once, it makes total sense and you'll never forget. Coming up with it on your own is sometimes another story with questions like #1.
