MCQ
A thin metallic spherical shell contains a charge $Q$ on it. A point charge $+q$ is placed at the centre of the shell and another charge $q'$ is placed outside it as shown in fig. All  the three charges are positive. The force on the central charge due to the shell is :-
  • A
    upward
  • B
    toward left
  • toward right
  • D
    zero

Answer

Correct option: C.
toward right
c
Note that there is no field inside the metallic shell.
