Question

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 central charge due to the shell is

Answer 1

Answer:

hope it will help you

Explanation:

The metallic spherical shell acts as a shield and do not allow the electric field outside to penetrate through it.

Hence, electric field inside shell due to Q and q

1

is zero.

Hence, no force will act on charge q.
