A solid, infinite metal cylinder of radius a = 1.5 cm is centered on the origin, and has charge density Ainner = -5 nC/cm. Surrounding this cylinder is a cylindrical metal shell of inner radius b = 3.0 cm and outer radius c= 4.5 cm. This shell is also centered on the origin, and has total charge density Ashell = +2 nC/cm. Ashell C a = 1.5 cm b = 3.0 cm C = 4.5 cm tinne Ainner = -5 nC/cm Ashell = +2 nC/cm a) What is the linear charge density, Ash,outer on the outer surface of the cylindrical shell? b) What is the surface charge density, Oinner, on the inner solid metallic cylinder which has radius ? c) If the shell is connected to ground, the charge density, Ash,inners On the inner surface (with radius b) of the cylindrical shell will increase, decrease or stay the same
