1. The problem statement, all variables and given/known data A, B and C have charges of -2.6, 8.5, and 7.5 microC respectively. These charges are at the points 2.5, 7 and 2 on a straight line where all distances are measured in millimeters from the zero point. What force does a -7.5 microC charge feel if it is at the point 1.2 mm? 2. Relevant equations F = k(q1q2)/r^2 3. The attempt at a solution I tried making free body diagrams and then using those to make net force equations but I was unsure how to find the force from the equations.
