## Homework Statement

Show that the maximum magnitude E

_{max}of the electric field along the axis of a uniformly charged ring occurs at x=a/(sqrt2) and has the value Q/(6(sqrt3)πε

_{0}a

^{2})

## Homework Equations

E=k

_{e}Δq/r

^{2}

## 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.
