...interested in the electric field? Consider a charged ring of radius 47.9 cm and total charge 12 nC.

We are interested in the electric field a perpendicular distance z away from the center of the ring.

In centimeters, at what distance from the center of the ring does the electric field become maximum?

Hint: The field for a ring of charge is:
