SUMMARY
This discussion focuses on finding and labeling equilibrium points between four point charges and determining their stability. The key method involves calculating the electric potential and its gradient, using the relationship E = -dV/dr. To find equilibrium points, one must differentiate the electric potential and set it to zero, solving for the distance r. The stability of these points is assessed by examining the second derivative, which indicates whether the point is a maximum or minimum, thus defining its stability as stable, unstable, or neutral.
