 _____________N/C

(b) What is the magnitude of the electric field at radial distance r = a/4?
 ______________N/C

(c) What is the magnitude of the electric field at radial distance r = a?
 ______________N/C

(d) What is the magnitude of the electric field at radial distance r = 1.60a?
 _________________N/C

(e) What is the magnitude of the electric field at radial distance r = 2.10a?
________________ N/C

(f) What is the magnitude of the electric field at radial distance r = 3.30a?
 _______________N/C

(g) What is the net charge on the inner surface of the shell?
 _______________fC

(h) What is the net charge on the outer surface of the shell?
 _______________fC
