Would it be F = k(q1q2)/r^2 ? so between A and the fourth charge, F = k(2.6*7.5)/(1.3)^2 and so on between B, C and the fourth charge

Homework Statement 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...
