Abstract

By applying the condition for stability of equilibrium and Gausss law, it is proved that any point charge cannot be held in stable equilibrium by electrostatic forces alone; the scope of application is emphasized, and corresponding teaching suggestions are put forward. 

Key words： electrostatic field; equilibrium stability; Gausss law
