I had one student come into my office hours on Thursday. She had a question on the homework. She set up the question properly but failed to convert to correct units (grams instead of kilograms), which threw off her final answer.
I had another student come into my office hours on Friday, and she had trouble applying the electric force equation to multiple chargers. We looked at an example from the homework, and I told her that we need to use the F = kQ1Q2/r^2 equation as normal, and use trigonometry to take into account for the angle. With a little trig refresher, we were able to work through the X-direction together and she was able to do the Y-direction on her own.
