Magnitude and direction of Net electric force

[joolivas]

I will like to know how to approach to this problem: Over the x-axis is Q1=60μC Q2=-80.0μC the separation between them is 50.0cm. There is a point A on the y-axis 40.0 cm above Q1, and a point B 40.0cm above Q2. I want to know how to approach to find the direction and magnitude of the Net electric field produced at A. Thanks in advance.
