q1 = 4.0 µC and q2 = 4.0 µCare located at r1 = (4.0î − 5.0ĵ + 2.0k) mand r2 = (9.0î + 5.0ĵ − 6.0k)m What is the force (in N) of q2 on q1? (Express your answer in vector form.)

- Relevant Equations
- F = k*q1q1/r^2

I tried using the distance between r2 and r1 and plugging them into the equation for i, j, k. >>

So for the force in the x direction it was k*(4E-6*4E-6)/(4-9)^2. The answer I got was wrong according to webassign. Can someone please tell me what I am missing?
