B. Hold a charged rod vertically upward. Take the charged pith ball (hold the wooden dowel) and move it to various positions around the rod. The picture below shows a

top view of the rod and the x's represent the various positions to hold the pith ball. Based on your observations, draw vectors to represent the net electric force on the pith ball at each of the points marked by an “X." Remember that the length of the vector is proportional to the strength of the force.
