Homework Statement
Charge q2 in the figure(Figure 1) is in static equilibrium. Assume that q = 4.4nC .
Figure:http://session.masteringphysics.com/myct/itemView?assignmentProblemID=31833513&offset=prev
what is q1 ( distance between q2 and q is 10com and distance between q1 and q2 is 20cm)
Homework Equations
F=k*q1*q2/(2d)^2 + k*q*q2/d^2 = 0
I then isolate for q1
The Attempt at a Solution
My answer is 1.7x10^-8 C which is wrong, I have converted all givens to Standard units
