2. We have a central wire (2D, cylindrical) of charge qo surrounded by a metal shell (2D, cylindrical) of inner radius r1 and outer radius r2, like a coaxial cable. We want to discuss how the charge rearranges itself within the shell as a result of the particle. Hint for Q: every nonzero charge region is infinitesimally thin in the radial direction. (a) Floating case. Draw Q(r), E(r), and In E(In r). Provide an expression for E(r) at r> r2. (Three plots, one expression) (b) Grounded case. Draw Q(r), E(r), and In E(In r). Provide an expression for E(r) at r> r2. (Three plots, one expression)
