===== Electrostatics and Vector Integrals ===== Here is a {{workshops:colombia10:Colombia10Integrals.ppt|link to the powerpoint presentation}} from this session. ---- We started with a small group activity calculating * dr vector in curvilinear coordinates. Then we calculated * the electrostatic potential due to a ring of charge. This calculation is just one activity in a [[:whitepapers:sequences:emsequence:start|sequence]] that allows students to build up their understanding of how to do complicated integrals on step at a time. We ended with a discussion of what the electrostatic potential looks like geometrically and how we might graph it. (See the graphs on the powerpoint presentation above.)
