Solve Electromagnetism: Gold Nugget Net Charge Problem

In summary, to find the net charge of a 1.0-g nugget of pure gold after removing 1.0% of its electrons, first find the mass of a gold atom from a table. Then, obtain the number of gold atoms by dividing 1.0g by the mass of a gold atom. Multiply this by the atomic number of gold to get the number of electrons. After removing 1.0% of these electrons, add the remaining electrons and protons to obtain the net charge. In regards to a long cylinder with uniform polarisation, the electric field inside the cylinder can be found, and the field outside the cylinder can be expressed as E=Rsquared/3 times

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
