Nonlinear Systems: The following nonlinear system is a model for the electric field between two point charges. Determine the equilibrium solutions, if any, and classify their stability. Then sketch the phase portrait by sketching h- and v-nullelines, drawing appropriate arrows between nullclines to determine direction of solution curves. ' =2ry -²-2²-1
