suppose you negatively charge a teflon rod by rubbing it with rabbit fur. which statement in the list is false? and why?
a) The rod can attract small bits of paper, due to microscopic polarization of the paper by the electric field generated by the rod.
b) The rabbit's fur will become positively charged.
c) If the rod is brought near a metal object, the object will become macroscopically polarized, with its free electrons pulling toward the rod leaving a deflict of negative charge on the other size.
d) rubbing the charged area of the teflon rod on another teflon rod will transfer some negative charge to the second rod.
e) None of the above statements are true.

After charging the plastic rod negatively by rubbing with the fur, bring it near to (but not touching) the proof plane and keep it there for a second. Then, while keeping the plastic rod near (but not touching) the proof plane, move the proof plane away from the grounded object. Once contact between the proof plane and the bar is broken, the rod is moved away. How does the proof plane acquire charge without touching the charged rod?
