1. The problem statement, all variables and given/known data Problem #13 on the attached picture (I can't retype a bubble diagram) 2. Relevant equations I honestly have no clue. I know I'm not supposed to say this because I'm supposed to read my textbook first, but this is not covered at all in my textbook, this is a unit my teacher added on to the curriculum, because she thought it would be cool. Furthermore, I was absent the day she taught this, and literally nobody I have asked for help understands how to do this either. I do know that one person mentioned to me something about a left/right hand rule, to identify the direction of charges. 3. The attempt at a solution No idea how to start, please, help me lol. I know that there are supposed to be x's that signify something. I also know whenever the lines split, deviate, or curve, some sort of collision has occurred. I've been googling around, but nothing I've found makes any sense to me. Context: I'm in high school, AP Physics 1, none of this is in my textbook, test is tomorrow, this is one of the practice problems my teacher gave me.
