Homework Statement


Show that the maximum magnitude Emax of the electric field along the axis of a uniformly charged ring occurs at x=a/(sqrt2) and has the value Q/(6(sqrt3)πε0a2)


Homework Equations


E=keΔq/r2


The Attempt at a Solution


I made the vertical components cancel along the axis from the top and bottom of the ring so that I just have the x-axis field, but I really don't know what else to do. I'm not even sure if that equation is the right one to use. This question seems to be made deliberately confusing.
