3. Charge lies on the circular disk r ≤ 4 m, and z = 0 m with surface density Os = 10-4/r C/m². Determine E at r = 0 and z = 3 m. (Mark 7) b. Assume that there is a region with cylindrical symmetry in which the conductivity is given by σ = 1.5e-150p kS/m. An electric field of 30 k V/m is present. a. Find J: Use J = σE = 45e-150p k kA/m2 b. Find the total current crossing the surface p < p 0, z = 0, all (Mark 7)
