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 $q_1$ is placed outside it as shown in figure. All the three charges are positive. The force on the charge at the centre is:
  • A
    Towards left.
  • B
    Towards right.
  • C
    Upward.
  • ✓
    Zero.
✓

Answer

Correct option: D.
Zero.

Electric field due to $Q\ \&\ q,$ inside the spherical shell is zero.
