Comparing the flux and the flux density through a Gaussian sphere as its radius is increased, the flux

  • A.falls as the inverse square while the density stays the same
  • B.and the density both fall as the inverse square
  • C.and the density both remain unchanged
  • D.stays the same while the density falls as the inverse square

Answer: D

The enclosed charge fixes the flux, and spreading it over an area growing as the square of the radius reduces the density accordingly. Keeping the two quantities distinct removes most of the confusion in Gauss's law problems.
