Concept #1: Gauss' Law
Example #1: Electric Field Within Spherical Conductor
Practice: Rank the flux through surfaces A, B and C in the figure below from greatest to smallest.
Example #2: Electric Field due to Hollow Shell
Example #3: Surface Charge Density
Practice: A spherical, conducting shell has a charge of –6C. If a 4C charge were placed at the center of the shell, what is the electric field at 4 cm? At 12 cm?
