Question

The sphere and ellipsoid in the figure below surround equal charges. Four students are discussing the situation. Student 1: The fluxes through A and B are equal because the average radius is the same. Student 2: I agree that the fluxes are equal, but that's because they enclose equal charges. Student 3: The electric field is not perpendicular to the surface for B, and that makes the flux through B less than the flux through A. Student 4: I don't think that Gauss' Law even applies to a situation like B, so we can't compare the fluxes through A and B. Which of these students, if any, do you agree with? Explain.

Explanation / Answer

Student 2 : - As the area increases , the electric field decreases by the same factor so that the fluxes are equal.
