3. A negatively charge ruler is brought near an electroscope
Charge Diagrams 1. Suppose that a positively charged rod is rubbed against the electroscope shown at right and transfers electroscope. The rod is then moved far away from the electroscope. Draw the position of the needle. Draw a charge diagram for the electroscope. Charging Plate...

Ground your electroscope. Touch a negatively charged rod to the metal plate of the electroscope. Draw in the schematic how the charges are distributed, and indicate the new deflection of the rotating pointer once it has come to equilibrium + Perform this experiment with the charge remaining from step 3. Recharge your negatively charged object and bring it into close proximity to the metal plate without touching. We are charging by induction in this case. How does the...

electric charges 1. When a rod of the same charge is rought close to the knob of a charged metal leaf electroscope, what is the effect on the metal leaves? Draw a sketch that explains that effect. 2. When a rod of the opposite charge is brought close to the knob of a charged metal-leaf electroscope, what effect does this have on the metal leaves? Again, draw an explanatory sketch. 3. what is the procedure for giving an electroscope a...

Questions 11, 12, and 13
Electric Charge 10. When the electroscope is charged negatively by induction, it acquires extra electrons. From where do these extra electrons come? The extra eevons come from grounding the eiectroscope wh a positively charged o vo the result mll be a negave charge. 11. How can you tell if an electroscope is charged? 12. Can an electroscope, by itself, show whether it contains positive or negative charge? 13. In an electroscope, do the gold foil...

PartI-Van de Graff Generator Demonstration: In this part of the experiment, the TA will require a few student demonstrators to perform the activity below before the class answers the questions that follow. The student volunteer must stand on the rubber mat next to the Van de Graff generator and place your hand on top of the generator. Have another volunteer turn the generator on. While the generator is charging, shake your head. 1. What do you observe? 2. What do...
