Earnshaw's theorem says that:
A collection of point charges cannot be maintained in a stable stationary equilibrium configuration solely by the electrostatic interaction of the charges.
I also know about this theorem being proved visually by Gauss' law, where there is this idea about a negative charge being there. But I want that case where there is a positive charge surrounded by other positive charges.
I know I am getting something wrong, but could you please explain what and why this is true or false?
