1. The problem statement, all variables and given/known data The question wasn't really written down. It was a question asked after an explanation, and it really wasn't straightforward. I'm going to try to make it into a intelligible thing. If there is a +3 charge and a -1 charge at a distance from one another, where to the right of these two charges would there be a point where the total electric field is zero? +3 ---------- -1 ----------- P 2. Relevant equations E=Qk/r^2 3. The attempt at a solution I'm not sure if I did the right things but this is what I did: I named the distance from +3 to P r1 and the distance from -1 to P r2. If the total electric field must be zero, then I think that the electric field due to +3 must be equal but opposite to the one due to -1. Maybe? So I put it like this: E1=-E2 Q1K/r1^2 = -Q2K/r2^2 I cancelled out the K. And for Q1 I put the +3 charge. For Q2 I put the -1 charge. (r2^2)*3=r1^2 r2=√(r1^2/3) The question didn't ask from where would the distance be measured, so I picked from the -1 charge. Would this be right?? Is Q only the magnitude?? Thank you!
