how do i go about solving for q in the equation:
(F x r x r)/k = (6.63E-6 -q)(q)
What are your knowns/unknowns and are there any additional equations?
I skimmed over your other thread, and you're trying to solve for q where the rest of the variables are known, right?
This is just a simple quadratic equation. Using factoring here obviously won't be useful since the numbers are a bit messy. Just arrange it to the general form ([tex]aq^2+bq+c=0[/tex]) and solve for q, and remember any limits you may have on its value because of its physical properties.
