Textbook Question
Chapter 5.1, Problem 3bT
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.

You have the same line of charge in the previous problem (with +6.00 nC of charge on it). But now you are measuring the electric field 1.5 m above the center of the rod – see image below. Predict the electric field at Point P in this diagram. Make sure to include a direction with your answer.
Solve the problem and draw and label a vector diagram in the given problem.
Part 1. Two charges A (+30 µC) and B (–40 µC) are 60 cm apart. What is the net field strength at a point midway between them?
Part 2. What is the net electric field intensity at a point 20 cm to the left of charge A in No.1? Assume that the point and the charges are collinear.
A hollow ball with radius R = 2 cm has a charge of -4 nC spread uniformly over its surface (see the figure). The center of the ball is at P₁ = cm.
