[QUOTE="gamma-guy, post: 5480048, member: 589830"] [h2]Homework Statement [/h2] So I was given some questions as practice, and I can't seem to do them. Here is a link to the questions: [URL]http://i.imgur.com/ZmkqCAV.jpg[/URL] (the answers are in square brackets) Ive only been able to calculate Q3 and Q2 so far. I would really especially like help with Q1. I've been stuck on it for ages. [h2]Homework Equations[/h2] Ive been told this would be helpful: [URL]http://i.imgur.com/nmrsk2E.jpg[/URL] [h2]The Attempt at a Solution[/h2] Ive been stuck on Q1 for ages. I've been playing around with F = k q1q2/r^2 but that's not getting me anywhere. For Q2: I used E = kq/r^2 for q1 and q2. Subtracting the answers gave me -225x10^3, which is somewhat equal to 2.3x10^5. I've got no idea on how to get the j vector component though. Edit: I just got the j vector. Pythag and then the formula above got it. I have no idea where to begin for Q4 ANY help appreciated. Thank you [/QUOTE]
