Two point charges are fixed on the y-a
Two point charges are fixed on the y-axis at the locationsshown in the figure above. A charge of +q is located at y= +a and acharge of +2q is located at y = -a. Express your answers to parts(a) and (b) in terms of q, a, and fundamental constants.
(a) determine the magnitude and direction of theelectric field at the origin.
(b) Determine the electric potential at theorigin.
A third charge of -q is first placed at an arbitrarypoint A (x= -x0) on the x-axis as shown in the figure below.

(c) Write expressions in terms of q, a, x0, andfundamental constants for the magnitudes of the forces on the -qcharge at point A caused by each of the following.
I. The +q charge
II. The +2w charge
