22.20: a) For points outside a uniform spherical charge distribution, all the charge can be considered to be concentrated at the center of the sphere. The field outside the sphere is thus inversely proportional to the square of the distance from the center. In this case: C N 53 cm 0.600 cm 0.200 ) C N 480 ( 2 = = E b) For points outside a long cylindrically symmetrical charge distribution, the field is

In this case C N 160 cm 0.600 cm 0.200 ) C N 480 ( = = E c) The field of an infinite sheet of charge is ; 2 / ε σ E = i.e., it is independent of the distance from the sheet. Thus in this case . C N 480 = E...
