5.
Remove one charge producer and note the electrometer reading. Replace the charge
producer and remove the other. Note the electrometer readings. Using the magnitude and
polarity of the measurements, comment on conservation of charge.
Extra Things to Try
1.
Try repeating Procedure 1A with the opposite charged wand.
2.
Try rubbing the white charge producer with a proof plane, then measure the magnitude
and polarity of the charges produced.
3.
Try rubbing the blue material with a proof plane. Measure the magnitude and polarity of
the charges produced.
4.
Construct a list of materials such that if a material lower in the list is rubbed with a
material higher in the list, the higher material is always positive.
