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 and the knob always have the same charge? If they do always have the same charge, explain why they do; but if they do not always have the same charge, give an example in which they do not. 14. What problems ca water, mosturg and humidity cause in this lab? 15.eribe the method of charging rods with cjoths or fur that avoids these problems 16. What is a possible consequence of placing too much charge on a gold foil electroscope? condnCtor Which can create problems for tnis idb 15.

Answer 1

11) when the elctroscope is charged the leaves are get separated from each other.

12) No, we can find it by the observations.

13) No, when we bring a positively charge object close to the knob then all the electrons get pulled towards the knob by leaving the gold foil leaves positive and they get separated at that condition knob and the foil do not have same charge.
