Suppose that the magnitude of the charge on the yellow sphere is determined to be 2q and at (d2cos(theta), -d2cos(theta). Calculate the charge q_red on the red sphere at (d1,0) with a positive blue sphere,q, at the origin and whose net force,F, is in the direction of -y. The yellow sphere is negative and the red sphere is positive. ( See picture bellow)(adsbygoogle = window.adsbygoogle || []).push({});

Express your answer in terms of q, d1,d2, and theta.

Well the Fx on blue due to the yellow sphere= k(2q)(q)/(d2cos(theta))^2

and the Fx on blue due to the red sphere = - k(q_red)(q)/(d1)^2

Now what? I am unsure as to what to do now. Any help would be appreciated.

Thank you.
