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 q1 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.
  • D
    Zero.
✓

Answer

  1. Zero.

Explanation:

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