Hold the charges rod horizontally. Use a charges pith ball to explore the region around the rod. On the basis of your observation, sketch a vector to represent the net electric force on the ball at each of the points marked by an “×.”
Is all of the charge on the rod located at a single point? (e.g., Is all the charge at the tip of the rod? At the middle?) Explain how you can tell.
On the basis of the vectors you have drawn, is it appropriate to consider the charged rod as a point charge? Explain.
