AP Physics C: E&M 2012 Multiple Choice Solutions (with Explanations)

Hope you find this video helpful! These are my worked solutions to the AP Physics C: Electricity and Magnetism 2012 Multiple Choice (MCQ) section. MISTAKE: 35:53 I should've said sine, not cosine. Cross-products involve sine, dot products involve cosine. Sin(theta) is at it's maximum when theta=90. Sorry! Thanks to b0b10 for pointing it out.

With this, I have made explanations to the 2012, 2009, 2004, and 1993 MCQs. If you want to see answers to the 1998 MCQ, watch Flipping Physics' video. I have also found a 2008 practice exam apparently released by Collegeboard at one point. I might make a video on that but I can't promise anything.
