Force between walls of faraday cage and charge inside

Click For Summary
SUMMARY

The discussion confirms that a charged sphere placed inside a spherical Faraday cage experiences a force of attraction towards the walls of the cage when moved closer. This phenomenon is explained using the concept of image charges, which allows for the calculation of the force exerted on the charged sphere by the cage's walls. The presence of the cage alters the electric field, resulting in this interaction.

PREREQUISITES
  • Understanding of electrostatics and electric fields

Is there a force in this case: For the sake of simplicity, a spherical Faraday cage. A smaller charged sphere inside. If we move the small sphere close to the wall of the cage, will there be a force of attraction between the wall of the cage and the small charged sphere?

Yes. You can find the force by using an image charge.
