Similar to what was observed in the ice pail experiment, the positive charge on the charged sphere attracted the negatively charged particles from the other sphere. This is why readings closest to the charged sphere appear negative, while the readings on the far side appear positive. No contact is necessary; the simple attractive forces cause the composition of charges to change in the affected sphere. Explain the charge distribution of the isolated sphere in steps 3 and 4. The isolated sphere experienced a negative charge on the side closest to the charged sphere, and experienced a positive charge on the side farthest from the charged sphere. Explain the results obtained for step 8. No residual charge was measured after the spheres were separated. This makes sense – without the charged sphere to redistribute the charges in the isolated sphere, the charge returned to a neutral composition throughout. Part 3:

If the charge remains constant during the separation of the plates why do you see a change in electrometer reading? The electrometer measures in volts, not Coulombs (Coulombs are the actual unit of charge). As such, even though the charge remains constant, the output in Volts will change with different distances between the plates. Results/Discussion: As discussed in earlier sections, these experiments are meant to highlight the behaviors and interactions between charges and charged objects. In particular, the law of charge conservation is demonstrated in each trial. It is clear that charges aren’t simply produced or created, in each experiment a charge was developed by separating protons and electrons. Additionally, it is clear that positive and negative charges have strong interactions with each other, as shown by the attraction between plus and minus charges in the second experiment. While there are no accepted values to compare our results against to develop a percentage error, our results do seem relatively accurate. The positive and negative charges came close to cancelling out (the desired result) in our first experiment, and readings in subsequent experiments served to confirm the laws that deal with charges. The experiment went smoothly, but some improvements could be made. First, the lab equipment could be more accurately labeled. There were several different charge paddles, but they were in various stages of disrepair and it was difficult to tell which were appropriate for each part of the experiment. Furthermore, more up to date electrometers could lead to more accurate results – the electrometer used for this particular experiment was difficult to use and rarely gave steady solutions.
