1. Concentric spherical conducting shells in free space of radii r1 = 0.00113 m and r2 = 0.00220 m have a potential difference of 20.0 V (let the inner shell be at 0 V and the outer shell be at 20.0 V). (a) Find V by solving Laplace's equation. (b) Find . (c) Find . (d) Find the surface charge density on the inner shell. (e) Find the charge on the inner shell. (f) Find the capacitance of the configuration.

2. Coaxial cylindrical conducting shells in free space of length 1.00 m and radii r1 = 0.344 m and ?2 = 0.457 m have a potential difference of 50.0 V (let the inner shell be at 0 V and the outer shell be at 50.0 V).
