Two small, copper spheres each have radius 1.00 mm. (a) How many atoms does each sphere contain? (b) Assume that
(a) How many atoms does each sphere contain?
(b) Assume that each copper atom contains 29 protons and 29 electrons. We know that electrons and protons have charges of exactly the same magnitude, but let's explore the effect of small differences (see also Problem 21.83). If the charge of a proton is +e and the magnitude of the charge of an electron is 0.100% smaller, what is the net charge of each sphere and what force would one sphere exert on the other if they were separated by 1.00 m?
