Textbook Question
Chapter 24, Problem 8CQ
The two spheres in FIGURE Q24.8 on the next page surround equal charges. Three students are discussing the situation.
Student 1 : The fluxes through spheres A and B are equal because they enclose equal charges.
Student 2: But the electric field on sphere B is weaker than the electric field on sphere A. The flux depends on the electric field strength, so the flux through A is larger than the flux through B.
Student 3: I thought we learned that flux was about surface area. Sphere B is larger than sphere A, so I think the flux through B is larger than the flux through A. Which of these students, if any, do you agree with? Explain.
