Would it still work in a similar manner as an actual electroscope where you would charge it either positively or negatively and then observe attractive or repulsive forces or is there an easier and more efficient method?

I get step 1, in which due to electrostatic induction the top part of electroscope gets positively charged while the leaves of electroscope become negatively charged. Now if we Earth the positively charged end of electroscope as shown in step 2, then electrons must flow from Earth to...

I'm trying to build a DIY metal leaf or pith ball electroscope. I want to provide it with a circular arc voltage scale visible directly behind the (deflected) ends of the leaves. To calibrate the scale with ballpark accuracy, I want to determine the charge density upon the leaf pair (or pith...

I know that if we bring a positively charged rod closer to the electroscope, charges of electroscope are separated and the leaves of the electroscope get away from each other. but what happens if we touch the positively charged rod with our hands and then move the hand and rod away?

Can we use Gold Leaf Electroscope to check whether a radioactive material gives off Alpha particles?

Homework Statement A positively charged rod is brought near the knob of an uncharged electroscope and the leaves of the electroscope diverge. As the positively charged rod is held near the knob, the electroscope is grounded with a wire. Then the grounding wire and the positively charged rod...

Hi I am running the electroscope experiment in vacuum. This is shown in (a) in the uploaded figure . Once the aluminum leafs are charged the chamber is pump down (b). As soon the pressure decrease low enough (around relative pressure of 30 inHg) the leafs collapse to each other abruptly. Here...

I want to make a electroscope but tried googling it and none made my criteria. What I want is a homemade electroscope that will give me a measurement, please tell what I would need and possibly a how to. Thank you

I am trying to measure the charge(or voltage) of a positively charged sphere by touching it with a non- calibrated electroscope. I am getting consistent results in the separation(or angle) between the metal leaves, but I don´t know how to calculate the voltage between the leaves from there. I...

A fully charged electroscope is touched with a neutral balloon. It is observed that the foil leaves of the electroscope are unaffected when the electroscope is touched w/ the balloon. Explain why the foil leaves were unaffected when the charged electroscope was touched by the neutral balloon...

Hey, I am helping out with a class and the students were given a question about an electroscope that is being charged by induction, and they have to label the charge distribution on a diagram. The diagram is drawn such that the conductive elements are separated - indicating a force between...

Question is posted in paint doc... I think it is C, because polarization will occur sending neg charge down to the leaves making them repel. is this correct?

Question: Can you use a pith-ball electroscope, to determine the charge of an unknown object? Is it possible?

Homework Statement When a flame is brought near a charged electroscope, the foil collapses. How is this explained? Homework Equations None The Attempt at a Solution Electrons are excited and given energy so distribute equally on the foil. Probably wrong. Please give correct...

Homework Statement As you are lying on the beach this past summer, you watch in awe as a super huge strato-nimbo-cummulus storm cloud roll in. You pull out your iphone and use the "electroscope" App allowing you to measure the charge on the storm cloud. It reads +40C. You tell your bf/gf...

Hi, My question is about gold-leaf electroscope induction experiment as it's shown here: http://en.wikipedia.org/wiki/File:Electroscope_showing_induction.png To spread out leaves you need to spend some energy, I'd like to know where it comes from Thank you!

What would happen to an electroscope if a wire from the negative or positive terminal of a battery is touched to an electroscope? Will the electroscope deflect or will it do nothing?

The theory I have read When you charge an electroscope with a negatively charged rod, electrons are repelled to the bottom of the electroscope and the gold leaf rises. Then when you shine light above the fundamental frequency on the top plate of the electroscope, electrons are liberated from...

Hello all, Q: If an electroscope is positively charged throughout (gold leaves are being repelled), and a very strong rod that is negatively charged, is progressively brought closer to the electroscope... How are the charges distributed? I think that as the negatively charged rod is...

If ultraviolet radiation is shone onto a freshly-cleaned zinc cap of an uncharged leaf electroscope, explain why the emission of electrons will soon stop I understand it is about the photoelectric effect, but I am not sure why the emission will ever stop... Thank You in advance!:biggrin:
