(a) About how many electrons are there in a copper penny, which has a mass of about $0.003 \mathrm{~kg}$ ?

(b) If you could isolate these electrons, how much charge would you have?

(c) Estimate the magnitude of the electric force it would require to bring one more electron to within $1.0 \mathrm{~nm}$ of these electrons, assuming they are combined to form one small charged object.

(d) Based on this force magnitude, do you think it would be possible to combine this amount of negative charge?
