8. If V(:::, y) is the voltage or potential at a point (my) in the spy-plane, then the level curves of V are called equipotential curves. Along such a curve, the voltage remains constant. Given that 16 \"E2 + 112 sketch the equipotential curves at which V = 4, V = 8, and V = 16. Be sure to label each curve with the appropriate voltage. Way) =
