Find the magnitude and direction of the force on the charge -Q on the figure in the attached document.
F = k(q)(Q)/r2r-hat
The Attempt at a Solution
So I have a force in the x direction and a force in the y direction.
Fx = k(Q1)(-Q)/(a) x-hat
Fy = (k)(Q2)(-Q)/(a) y-hat
F = Fx + Fy = -kQ22/(a)2 x-hat + -kQ12/a2 y-hat
Is this right? Or can more be done to solve it?
