Explain why a neutral electroscope can NOT be used to identify the type of charge carried by a charged rod.

Homework Answers

Answer #1

A neutral electroscope cannot be used to identify the type of charge carried by a charged rod because if either positive or negative charge is brought near its knob, it will behave in a similar way. If positive charge is brought near it, positive charges are repelled in its known and they reside in its stem which diverge away from each other. If negative charge is brought near it, the negative charges are repelled and again the stems diverge. So, same result in both. Thus, neutral electroscope cannot be used to identify the type of charge.

A student grounds an electroscope by touching the top sphere with her finger, causing the leaves to hang down in a neutral position, then removes her finger. She then brings a negatively charged plastic rod close to the electroscope without touching it and the leaves open, repelling each other. What is the net charge on the entire electroscope

An inquisitive student touches an electroscope with his finger, and a second student then brings a charged plexiglass rod near the electroscope but does not touch it. The first student removes his finger from the electroscope before the second student removes the plexiglass. Meanwhile a third student touches a different electroscope with a charged PVC pipe. Are both electroscopes charged? If so, are they the same charge or different charges? Explain your reasoning. Feel free to include any drawings or...

Consider two charged conductors named A and B. These conductors are identical except for the charge they carry. An ebonite rod, which was charged by rubbing it with fur is brought near each sphere. Conductor A is attracted to it while conductor B is repelled by it. The rod is removed and the two conductors are brought into contact with one another and then separated. The rod is brought back near the conductors and now both are repelled by it....
