Earnshaw's Theorem: Stability in Electrostatics? - Physics Forums
Oct 18, 2014 · If the charge in the middle is displaced axially , then the electrostatic force will force it back into the equilibrium position.So isn't the charge in stable equilibrium. Isn't this a violation of …
Is the Equilibrium of the Negative Charge at Point A Stable or Unstable ...
Jun 3, 2012 · It is concluded that the negative charge is in stable equilibrium along the y-axis but unstable along the x-axis due to the greater force acting on it when displaced. The conversation …
Is This Equilibrium Stable or Unstable? - Physics Forums
