[QUOTE="Sylvia, post: 4998958, member: 534404"] [h2]Homework Statement[/h2] [ATTACH=full]175907[/ATTACH] [/B] In the above figure, if [I]Q[/I]1 and [I]Q[/I]2 are positive, where could a negative charge be placed and have a vertically upward net force on it? [h2]Homework Equations[/h2] F = k|q||q| / (r^2) [h2]The Attempt at a Solution[/h2] I wrote the force equations for the negative charge and both positive charges, but I have no idea how to proceed from there.
