Question

1. A positively charged insulator is brought close to an isolated touching) neutral conductor (without a) The diagram shows the positively charged insulator next to the neutral conductor. Draw the charge distribution on the conductor. Only draw the unbalanced charges. Insulator Conductor b) Draw an arrow on the conductor showing the direction and magnitude (indicated by the length of the arrow) of the net electric force caused by the insulator on the conductor. Label this Fa. (Fa means the force on the conductor by the insulator.) If 0 write =0. Draw an arrow on the insulator showing the direction and magnitude (indicated by the length of the arrow) of the net electric force caused by the conductor on the insulator. Label this Fic. If 0 write =0. 2. A positively charged insulator is brought near an initial neutral conductor with a grounding wire available. a) The conductor is now grounded by attaching a conducting wire between it and the ground. Draw the charge distribution on the conductor after the grounding wire has been attached. b) Consider two different situations: (1) The positively charged insulator is removed from the vicinity of the grounded conductor and then the grounding wire is removed. The conductor is now (circle one) positive negative neutral (2) The grounding wire is removed first and then the positively charged insulator is removed. The conductor is now (circle one positive negative neutral
