At a radius \( r \) inside a solid sphere carrying uniform volume charge density, the enclosed charge grows as

  • A.\( r^3 \)
  • B.\( r^2 \)
  • C.\( r \)
  • D.the total charge

Answer: A

The volume within radius r grows as the cube, and with the density constant so does the charge. Dividing by an area growing as the square leaves a field rising linearly, which is the standard result for the interior of such a sphere.
