Homework Statement:

An xyz coordinate system contains three charged particles: particle 1, q1=5.0 muC, at (4.0m,2.0m,0); particle 2, q2=12 muC, at (1.0m, 2.0m, 0); and an electron at (1.0m,0,0).
(a) Draw a diagram showing the vectors you need in order to determine the direction of the separate electric forces exerted on the electron by particles 1 and 2.
(b) Calculate the vector sum of these two forces.
Relevant Equations:
 f=k((q1*q2)/r^2)*unit vector r
I draw the graph like this:
For (b), I divided each force vector to e from p1 and p2 as x and y parts.
I computed them and got
Fx=4.608*10^(15)N
Fy=2.52*10^(15)N
However, I am not sure whether I did it correctly or not...
I appreciate every help from all of you!!
Thank you!!
