Consider a cylindrical shell of inner radius a = 1.10 cm, outer radius 2a, and length L = 2.05 m. This cylinder has a total charge Q = 138 nC. This cylinder has a nonuniform charge density that depends on the distance from the axis r, given by ? = mr + c. The charge density reaches zero at the outer surface of the cylinder.
a) find constants m and c
b) find electric field at r=0.6cm, r=1.8cm, r = 3.6cm
c) Find the potential difference between the inner and outer surfaces of the cylindrical shell.
