75. The radius of the cylinder (0.020 m, the same as r B ) is denoted R , and the field magnitude there (160 N/C) is denoted E B . The electric field beyond the surface of the sphere follows Eq. 23-12, which expresses inverse proportionality with r : G E E R r rR B =≥ for . (a) Thus, if r = r C = 0.050 m, we obtain G E == 160 0 020 0 050 64 b gb g b g .. N C . (b) Integrating the above expression (where the variable to be integrated,
