This problem has been posted before with different values for each variable and I did as best I could to complete it similarly. However, when I attempt to input my final answer I get it wrong every time. I just wanted to see where I am going wrong, thanks. 1. The problem statement, all variables and given/known data Coulomb's law for the magnitude of the force F between two particles with charges Q and Q' separated by a distance d is: |F| = K(|QQ'|)/d2 Consider two point charges located on the x axis: one charge, q1 = -14.5nC, is located at x1 = -1.745m the second charge, q2 = 36.5nC, is located at the origin. What is the net force exerted by these two charges on a third charge q3 = 45.5nC, placed between q1 and q2 at x3 = -1.085? Your answer may be positive or negative, depending on the direction of the force 2. Relevant equations K = 1/4[itex]\pi[/itex][itex]\epsilon[/itex]0 3. The attempt at a solution I found the distance between q1 and q1 to be 0.660m I found the distance between q3 and q2 to be 1.085m I began by finding the charge q1 exerts on q3 by: |F1| = K*[|(-14.5*45.5)|/(0.6602)] = 1.362E13 (At this point in the problem there is a hint section asking for this force, when I submit the answer I calculated I am told it is wrong.) And then I found the charge q2 exerts on q3 by: |F2| = K*[|(45.5*36.5)|/(1.0852)] = 1.268E13 (Again, there is a hint section asking for this value, which also tells me it is wrong) From those two calculated forces I take F1 - F2 to get a final answer, which is ultimately deemed incorrect. Any help would be appreciated!
