The drawing shows a situation in which charges are placed on the x and y axes. They are all located at the same distance of 45.4 cm from the origin O. Determine the magnitude of the net electric field at point P, where P is also 45.4 cm from the origin.  

In a region of space, the electric potential decreases uniformly from east to west, and does not vary in any other direction. The electric field:
