Solve Electromagnetism: Gold Nugget Net Charge Problem

[y1k8a]

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?

 

[y1k8a]

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
