A2L Item 124

Goal: Link flux and enclosed charge.

Source: 283-410 Flux greatest?

Consider the flux through the following spherical Gaussian surfaces.
Take each charge distribution to be either a point charge or a spherical
shell of charge (uniformly distributed). For which situation is the flux

  1. a and c
  2. a, b, and c
  3. b
  4. a
  5. b, c, and e
  6. a, f, and g
  7. b, c, and g
  8. Other



(2) All these have the same flux. Some students do not read the question
carefully and think the number of ‘+’ signs matter.
