It is no longer net neutral on a microscopic level. 2. Polarization with Neutral Pith Balls and Charged Rods: To explore electric polarization effects, you will move a charged rod very close to the pith balls, without actually touching them. See Figure 2 for an diagram explaining electric polarization, with l\"plus" and "minus" symbols for charge that hopefully reminds you about learning induced dipole forces a prior chemistry course. In this procedure, do not touch the pith balls with the external charging rod. If the rod touches the pith balls, then charge may be transferred and you will no longer be inducing a force from electric polarization. If the pith balls are charged at any point. touch them with your ngers, and the friction should remove charge. Figure 3 shows an example picture of the pith balls. Note that you can determine whether the pith balls are charged, based on how they are hanging. The pith balls are made from the same material; the coloring is dye purely for aesthetics. a. State a qualitative electrostatic induction question that you can answer in an experiment using a charged rod and the neutral pith balls, where you DO NOT touch the charging rod to the pith balls at any time. b. State a physics model prediction for your experimental results. c. Draw 8. describe relevant aspects of your experimental setup that will allow for you to compare your results to your prediction
