A glass rod transferred 6.242x10^11 electrons to an electroscope. What is the charge on the electroscope?
Charge of 1 electron = 1.6*10^-19 C
Charge on 6.242x10^11electrons is 6.242x10^11 *1.6*10^-19 C = 9.9*10^-8 C
charge on the electroscope is 9.9*10^-8 C
A glass rod transferred 6.242x10^11 electrons to an electroscope. What is the charge on the electroscope?
An electroscope has a charge of −2.2 µC while your finger has a charge of 2.5 µC. You touch the electroscope with your finger and discover that the charges of your finger and the electroscope are now the same. In this process, electrons were transferred from the electroscope to your finger. How many electrons were transferred in order for your finger and the electroscope to have the same charge?
3 charge diagram questions: 1. A positively charged rod is rubbed against an electroscope 2. A positively charged rod is brought closed to an electroscope 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...
an electroscope has been given a charge of +5q and the leaves are separating apart. What is the final status of the leaves of electroscope if rod with a charge of -3q is touched to the electroscope knob?
Q5 Scenario: Charge by induction of an electroscope needle by rubbing the hard rubber rod vigorously with a sheet of wool. a) What charge does the rubber rod have? Explain. b) Does the wool have an opposing charge? Explain.
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...
2.3.2 Charge the Electroscope Directly An electroscope can be charged directly by transferring charged particles to it from a charged conductor. In the previous lab, we built a device for placing charge on a conductor, an electrophorus. The video shows charging the elec- trophorus and directly transfering charge to the electroscope by bringing the pie pan into contact with the paper clip- Observe-2.5:Could your electroscope be charged directly? Draw-2.6:In the box to the right draw the location of the electroscope...
An electroscope has been given a charge of +5q and the leaves are separating apart. What is the final status of the leaves of electroscope if a rod with a charge of -39 is touched to the electroscope knob? +59 Leaves will open more. No change will happen. Leaves will close all the way and then re-open with opposite charge. Leaves will close, but not all the way. Leaves will close all the way.
A negatively charged rod is brought near an electroscope without touching it. The leaves are initially separated, and as the rod is brought closer, the leaves move further apart. What is the charge on the electroscope?
An electroscope is charged by touching it with a negatively charged rod. The electroscope leaves spread apart and the rod is removed. Then another, negatively charged rod is brought near the top of the electroscope without touching. What happens? A. You are unable to make the observation because the rod is attracted to the top of the electroscope causing them to touch after all. B. The leaves do not change their position. C. The leaves move closer together. D. The...
An electroscope has been given a charge of +2q and the leaves are separating apart. What is the final status of the leaves of electroscope if a rod with a charge of -39 is touched to the electroscope knob? +29 Leaves will close all the way and then re-open with opposite charge but will be less open than initially. Leaves will close all the way. No change will happen. Leaves will open more. Leaves will close all the way and...
