Homework Statement
Hi,
Having some trouble with answering this question:
A thin nonconducting rod with a uniform distribution of +'ve charge 'Q' is bent into a circle of radius R. There is an axis, 'z' which originates in the center of this ring.
In terms of 'R', at what +'ve value of z is that magnitude maximum?
I'm not precisely sure what this question is asking (slightly ambiguous), however I'm assuming it's asking where the electric field due to this ring is at a maximum. Any help is appreciated!
Homework Equations
E = (q*z*K)/(Z^2 + R^2)^(3/2)
E = F/Q
Where K = 1/(4*Pi*E(naught))
The Attempt at a Solution
I have determined z in terms of R to be
z = R/Tan(Pi/2 - Theta)
Where 'Theta is the angle of elevation between the 'point' on z and the edge of the ring.
Thanks!
