A thin, metallic spherical shell contains a charge Q on it. A point charge q is placed at the center of the shell, and another charge q₁ is placed outside it as shown in the figure. All three charges are positive. The force on the charge at the centre is:

Question

Philoid · Accepted Answer

Charge q₁ will only affect the outside charge Q. However, a charge can only induce charge on the surface of the conductor, but not on any charge inside it. Hence, there will be no force on the charge inside the conductor, q.
