Homework Statement
At a particular moment, three small charged balls, one negative and two positive,are located as shown in Figure 13.46. Q1 = 3 nC, Q2 = 7 nC, and Q3 = -6 nC.
What is the electric field at the location of Q1, due to Q2?
Homework Equations
[tex]\vec E = q1q2\hat{r} / 4\pi\varepsilon r^2[/tex]
The Attempt at a Solution
r = <0, .04, 0> m
rmag = .04
rhat = <0, 1, 0>
E = [3e-9(7e-9)(9e9)] / .0016
Which gives me:
E = <0, 1.18125e-4, 0>
What am I doing wrong here? At first I figured I missed a negative, so I tried making my answer negative, but apparently that's not the case.
