If I rub a plastic rod with wool, and bring it near a small piece of aluminum foil on an insulting table, the foil will jump up toward the rod. If I rub that same rod with rabbit fur, the foil will feel a force away from the rod.
Group of answer choices
True
False
The statement is false as we rub the Plastic rod with a wool or rabbit fur, then the plastic rod is negatively charged due to transfer of electrons from the wool as well as from the fur. Due to this the rod geta negatively charged in both of the cases , so in both of the cases the foil will jump towards if it is positively charged or go away if it is negatively cjarged. But it will not go towards in one case and away in the other case.

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?
Create a bunch of tiny bits of paper from some scratch paper, and scatter them on a table. Locate as many different types of cloth from your closet or drawers as you can. Cotton, silk, polyester and wool are the most common. Next locate as many different types of plastic pens, like colored ones and clear acrylic ones. If you have a plastic ruler, have that handy too. In a uniform fashion, try as many cloth/plastic combinations you can and...
