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?
