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
greatest?
- a and c
- a, b, and c
- b
- a
- b, c, and e
- a, f, and g
- b, c, and g
- Other
Commentary:
Answer
(2) All these have the same flux. Some students do not read the question
carefully and think the number of ‘+’ signs matter.
