Thank you for your help! :smile:

Ok, so could I do this? Since Ex = 2/√2*(q1 - q2)*(ke/(2a2)) Ey = 2/√2*(q1 + q2)*(ke/(2a2)) Then (q1 - q2) = (Ex * a2*√2)/ke + (q1 + q2) = (Ey * a2*√2)/ke -------------------------------- q1 = (a2*√2)/ke * (Ex + Ey) So then q2 = (a2*√2)/ke * (Ey - Ex) Is that correct?

Thank you! And no I am not. I am supposed to just use Ex and Ey as variables.
