I did not do this. I am not sure where to substitute it in for or why I would do such a thing. Clearly a/2 is the point between two disks, but I do not know which of the variables in my general equation I would replace with a/2 or the formula that Mastering Physics gave me.

Homework Statement Consider two thin disks, of negligible thickness, of radius R oriented perpendicular to the x axis such that the x axis runs through the center of each disk. (Figure 1) The disk centered at x=0 has positive charge density η, and the disk centered at x=a has negative charge...
