Question

need work shown because i dont understand

Uniform volume charge density p A thick-walled, hollow cylinder has a volume charge density of p, where the charge is distributed uniformly within the walls, i.e., for R, <R< R2. (a) is this cylinder an insulator or a conductor? Explain. (b) find an expression for the electric field for three regions, (i) R< R1, (ii) R; <R< Ry, and (iii) R > R2 R1 R2

Answer 1

a) charge is uniformly within insulator as for distributed walls so it is a conductor lies on the su eurface of walls Electric field ELRI Using Gauss law f .dž - a E (47 (²) = b ola E=0 ㅠ R, < s < Rg Go ㅋ E (972 8 [1821)-AR} ] 7.
