Two small copper spheres each have radius 1.00 mm (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). 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?

Problem:

If Atoms Were Not Neutral... Because the charges on the electron and proton have the same absolute value, atoms are electrically neutral. Suppose this were not precisely true, and the absolute value of the charge of the electron were less than the charge of the proton by 0.00100%. (a) Estimate what the net charge of this textbook would be under these circumstances. Make any assumptions you feel are justified, but state clearly what they are. (Hint: Most of the atoms in this textbook have equal numbers of electrons, protons, and neutrons (b) What would be the magnitude of the electric force between two textbooks placed 5.0 m apart? Would this force be altractive or repulsive? Estimate wha the acceleration of each book would be if the books were 5.0 m apart and there were no non electric forces on them (c) Discuss how the act that ordinary matter is stable shows that the absolute values of the charges on the electron and proton must be identical to a very high level of accuracy.
