okay, I re-set up the equations to look like [(9x10^9)(3.1x10^-9)(q2)]/.1^2=(9x10^9)(q1)(q2)/.2^2 And I know that I have to solve for q1, but I don't understand how I am supposed to do that without the value for q2. How do I solve for q2 or is there something I'm not seeing where I don't have...

q1___________Q___________q2 10cm 10cm In the figure above the charge in the middle is Q=-3.1nC. For what charge q1 will charge q2 be in static equilibrium? Relevant equations I think that F=kq1q2/r^2 is relevant my attempt at a solution Since the ions are...
