Unformatted text preview: deﬁned by cos θ ≥ cos α . a)What is E (0)? When α → 0 and z → ± 1, what are E ( ± e z )? Note, in this case if you used Gauss’s law and incorrectly allowed the charge on the surface to be included in the total charge you would get a diferent (incorrect) answer. What is that answer? Now use a program like Mathematica and accurately graph E ( z e z ) vrs z for the following cases: a)z=(0,2), for cos α = 0 . 999 , ,. 999 b)z=(0,2) for cos α = 0 . 999 , ,. 999 Why does E change discontinuously at z=1 in case b, but not at z=1 in case a? 1...
