Aspherical shell with an inner radius $'a'$ and an outer radius $'b' $ is made of conducting material. A point charge $+Q$ is placed at the centre of the spherical shell and a total charge $- q $ is placed on the shell.

Charge $- q $ is distributed on the surfaces as

115-903

  • A

    $- Q$ on the inner surface, $- q$ on outer surface

  • B

    $- Q$ on the inner surface, $- q + Q$ on the outer surface

  • C

    $+Q$ on the inner surface, $-q - Q$ on the outer surface

  • D

    The charge $-q$ is spread uniformly between the inner and outer surface.
