1. The problem statement, all variables and given/known data Three charges, Q1, Q2, and Q3 are located in a straight line. The position of Q2 is 0.323 m to the right of Q1. Q3 is located 0.125 m to the right of Q2 In the above problem, Q1 = 1.37 μC, Q2 = -2.53 μC, and Q3 = 3.43 μC. Calculate the total force on Q2. Give with the plus sign for a force directed to the right. 2. Relevant equations F=kq1q2 / r^2 3. The attempt at a solution I used the above formula to find the force for charge 1-2, and charge 2-3, and then added them together. I got the wrong answer. My answers were: 0.29867 N + 4.99 N = 5.29 N What am i doing wrong !?
