What is the electrostatic constant?

Paper strips attracted by a charged CD. Electrostatics is a branch of physics that deals with the phenomena and properties of stationary or slow-moving electric charges. Since classical physics, it has been known that some materials such as amber attract lightweight particles after rubbing.
