Homework Help: Physics (2)

Posted by Andrew on Thursday, February 11, 2010 at 9:20pm.

Consider a charged ring of radius 43.4 cm and total charge 18 nC.

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

At what distance from the center of the ring does the electric field become maximum

..so E=kQ/(x^2)at a maximum distance...

how would i solve for x without E? ..sorry, im really confused with this question..
