Previous question : A -3 nC point charge is located at (1 m,0), and a -16 nC point charge is located at (0, 2 m). What are the magnitude and direction of the net electric field at the origin? Write the magnitude and the angle. Please help solve problem in picture. Please show work I want to learn the material :)

In the setup of the previous question, an additional charge 5 n0 is placed at the origin. Now calculate the total Electric field due to the three charges at the point P (1,2). What are the components of the electric field at P? (E_x, E_y) (144,6.75) (140,125) (-1 48,-1 4.75) (-1 40,1 .25)
