## Homework Statement

## Homework Equations

F=K

_{e}q1q2/r

^{2}

## The Attempt at a Solution

Using Coulomb's Law, here's what I've worked out:

F

_{AB}=0.593N

F

_{AC}=0.309N

F

_{x}=0.309 - 0.593cos60°= 0.0125

F

_{y}=0.593sin60° =0.514

√(0.0125

^{2}+ 0.514

^{2}) = 0.514 N/C

and θ = tan

^{-1}(0.514/0.0125) = 88.6°

I'm not sure why webassign is telling me that my answer is wrong. I worked out a problem almost exactly like this with slightly different numbers and got it right...
