$A$ non-conducting solid sphere of radius $R$ is uniformly charged. The magnitude of the electric field due to the sphere at a distance $r$ from its centre:

  • A
    Increases as $r$ increases for $r < R$
  • B
    Decreases as $r$ increases for $0 < r < \infty$
  • C
    Decreases as $r$ increases for $R < r < \infty$
  • D
    Both $(a)$ and $(c)$
