5 Number of electrons Copper consists of atoms that each have 29 electrons and mass 1.06 x 10-25 kg. Copper has a density of 8.69 kg/m3 mo. Assume that the copper is electrically neutral. b) Suppose that electrons are removed from the copper so that it has a net charge of 5.0 x 10-9 C (this is a typical number for capacitors in electronic circuits). Determine the number of electrons that have been removed. c) What fraction of the total...

A 0.68-mm-diameter copper wire carries a tiny current of 2.4 μA . The molar mass of copper is 63.5 g/mole and its density is 8900 kg/m3. NA=6.02×1023. Estimate the electron drift velocity. Assume one free electron per atom.
A thin, horizontal, 20-cm-diameter copper plate is charged to -4.4 nC . Assume that the electrons are uniformly distributed on the surface What is the strength of the electric field 0.1 mm above the center of the top surface of the plate? What is the strength of the electric field at the plate's center of mass? What is the strength of the electric field 0.1 mm below the center of the bottom surface of the plate?
A 52.8 g ball of copper has a net charge of 2.7 µC. What fraction of the copper's electrons have been removed? (Each copper atom has 29 protons, and copper has an atomic mass of 63.5.) What is the charge on the sphere contributed by protons? How many total protons are there?
