Homework Statement
There are three charges on the x-axis labled q1 = 9.9 uC, q2= -5.1 uC, q3 = ?
The distance between q1 at the origin and q2 is 0.1 m, what is the equilibrium distance between q3 and q1, and does that distance depend on the polarity of q3 ?
Homework Equations
F = (k*|q1|*|q2|) / (r^2), k=8.99E9
E = F / q
The Attempt at a Solution
In this system there are 4 different force vectors, for euilibrium they must cancle out F1+F2+F3+F4= 0.
|----------d----------|
q1--------q2--------q3; I don't think that d matters if q3 is + or - even if q3 where between
|---0.1m---|
q1 and q2 like this
|---d----|
q1------q3-------q2
|-------0.1m------|
