Ch23 Homework Solutions

23.27.A uniformly charged ring of radius 10 cm (0.10 m) has a total charge of 75 microCoulombs. Find the electric field on the axis of the ring at

(a) 1.0 cm = 0.01 m

(b) 5.0 cm = 0.05 m

(c) 30 cm = 0.30 m

(d) 100 cm = 1.0 m

from the ring.[ These solutions say "23.31" because this was problem 31 in Serway's

fourthedition. But that is the same as problem27in thisfifthedition. I havenotgone to the trouble tochangeall these. ]
