A thin nonconducting rod with a uniform distribution of
Chapter , Problem 24(choose chapter or problem)
A thin nonconducting rod with a uniform distribution of positive charge Q is bent into a complete circle of radius R (Fig. 22-48). The central perpendicular axis through the ring is a z axis, with the origin at the center of the ring. What is the magnitude of the electric field due to the rod at (a) z ! 0 and (b) z ! &? (c) In terms of R, at what positive value of z is that magnitude maximum? (d) If R ! 2.00 cm and Q ! 4.00 mC, what is the maximum magnitude?
