1. The problem statement, all variables and given/known data A positive charge +q1 is 3.00m to the left of a negative charge -q2. The net electric field is zero 1.00m to the right of the negative charge. Determine the relative magnitude of the charges in a ratio q1/q2 2. Relevant equations E=kQ/r^2 3. The attempt at a solution I set it so that kQ1/r1^2=kQ2/r2^2 but I'm not sure how to solve for the ratio? would the k's cancel out and it'd just be a ratio of the distances? Are the distances r1=4.00m and r2=1.00m?
