The blog is a part of the WebTA project for the McGill University Physics 102 class on Electricity and Magnetism. A link to the static site containing examples, explanations, etc. can be found in the sidebar.
Welcome
The purpose of this blog is to provide an additional avenue for students to ask questions and get explanations for the physics 102 course at McGill University. Questions can be asked by commenting, which for the time-being can be done annonymously. Questions can also be asked via the email address below (please use a McGill email address for this), but will not be answered on an individual basis. I will also be popping into the webCT discussion board this year, so questions from there may also appear here.
If you have come across this site from somewhere else, please do feel free to use it as a resource. I would ask that you not post new questions as I will have to restrict the commenting function if I sense that questions from students in the course are being drowned out by others. For complete "rules" of posting see: A few groundrules.... This worked well last year, so let's keep with it.

Hi, I was wondering how to calculate both a force and an electric field when you're only given one charge. For example, if I have a positive test charge q, and a positive charage Q1 r distance away from the test charge... I'm confused on how I can calculate the force vector (resultant) in order to set up a triangle and find the x and y components of the force (same for electric fields).
