Homework Help Overview

The discussion revolves around a problem in electromagnetism concerning the net charge of a gold nugget after a specific percentage of its electrons are removed. The subject area includes concepts of charge, atomic structure, and basic calculations related to the properties of gold.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss methods to calculate the number of gold atoms and electrons based on the mass of the gold nugget. There is an exploration of how to determine the net charge after removing a percentage of electrons. Some participants question the correctness of their approach to finding the net charge.

Discussion Status

The discussion is ongoing, with participants providing hints and exploring different interpretations of the problem. Some guidance has been offered regarding the calculation of the number of atoms and electrons, but there is no explicit consensus on the overall approach to finding the net charge.

Contextual Notes

Participants are working under the constraints of a homework assignment, which may limit the information they can use or the methods they can apply. There is a focus on ensuring that the calculations align with the properties of gold and its atomic structure.

1. Suppose a 1.0-g nugget of pure gold has zero net charge. What would be its net charge after it has 1.0% of its electrons removed?
please help! i don't know what to do

1. Find the mass of a gold atom from a table.
2. Obtain the number of gold atoms. i.e. (# of atoms) = 1.0g / (mass of a gold atom)
3. (# of electrons) = (# of gold atoms) x (atomic number of gold)

I guess this is enough for the hint?
 
after obtaining the electrons, i will get the 1% of electrons removed then ill add the electrons and protons to obtain the net charge? am i correct?
 
A very long cylinder of radius R, carries a uniform polarisationP perpendicular to it's axis.Find the electric field in side the cylinder. Show that the field outside the cylinder can be expressed in the form
E=Rsquared divided
