After you are done with the initial measurements (in other words, have completed Step #10). how would you verify that your puffs haven't discharged too much? This can be verified several times by moving test puff to and from the stationary puff. The same displacement of the test puff results should be the same at each distance, regardless of the charges when moving to and from the test puf During the experiment, you qualitatively measured how one charged puff moves in response to a charged source. You can now use the numbers you have recorded to glean a quantitative understanding of how the two puffs repelled one another. From the earlier discussion in the lab, we know the square of the separation is related to the displacement of the test puff
