(a,-3a). The charges are Q1=3q...

Two charges are located at (x1,y1) = (3a, -a) and (x2,y2) = (a,-3a). The charges are Q1=3q and Q2=q.

Part A: Find the electric field at the origin in E = Ex ̂ +Ey ̂ form in terms of k, a, and q. Be sure to draw and label a picture and show all of your work.Part B: What is the angle the E-field due to these two charges makes at the origin with respect to the positive x-axis (please answer as a positive angle corresponding to counter-clockwise rotation).
