1. The problem statement, all variables and given/known data Calculate the magnitude and direction of the Coulomb force on each of the three charges shown in Figure P15.10. http://www.webassign.net/sf5/p15_10.gif thats 3 cm if its to small to see. 6.00 µC charge Magnitude 1.50 µC charge Magnitude -2.00 µC charge Magnitude 2. Relevant equations F = K|q1||q2|/r^2 3. The attempt at a solution I tried this problem and it said i was incorrect but within 10% to the answer and that my rounding is off or something. this is what i did: 8.9875 x 10^9 (6 x 10^-6)(2 x 10^-6)/.05^2 (converted to m and C) .10785/.05^2 = 43.14 N That looks correct but it is saying im off. It say that im within 10% to the answer. Can anyone look at this and tell me what im doing incorrectly? For the other 2 I am not sure what to do, but i gave it a try for 1.5uC i did K(1.5 x 10^-6)(2 x 10^-6)/.02^2 this completely got me the wrong answer and not sure where to start on this.
