There is a solid sphere of radius $‘R’$ having uniformly distributed charge throughout it. What is the relation between electric field $‘E’$ and distance $‘r’$ from the centre ( $r$ is less than R ) ?

  • A

    $E \propto {r^{ - 2}}$

  • B

    $E \propto {r^{ - 1}}$

  • C

    $E \propto r $

  • D

    $E \propto {r^2}$
