In the Millikan oil-drop experiment illustrated in Figure 15.21, an atomizer (a sprayer with a fine nozzle) is used to introduce many tiny droplets of oil between two oppositely charged parallel metal plates. Some of the droplets pick up one or more excess electrons. The charge on the plates is adjusted so that the electric force on the excess electrons exactly balances the weight of the droplet. The idea is to look for a droplet dial has the smallest electric force and assume it has only one excess electron. This strategy lets the observer measure the charge on the electron. Suppose we are using an electric field of 3 104 N/C. The charge on one electron is about 1.6 1019 C. Estimate the radius of an oil drop of density 858 kg/m5 for which its weight could be balanced by the electric force of this field on one electron. (Problem 42 is courtesy of E.F. Redish.

A 50.0-g piece of aluminum has a net charge of +4.20 C. Aluminum has an atomic mass of 27.0 g/mol, and its atomic number is 13. a. Calculate the number of electrons that were removed from the initially neutral aluminum to produce this charge. b. Determine what fraction of the original number of electrons this removed number represents. c. By how much did the original mass of the aluminum decrease after charging?
An electric field does 1.50 103 eV of work on a carbon nucleus of charge 9.61 1019 C. Find the change in the nucleus (a) electric potential and (b) electric potential energy in joules.
If electrons are negatively charged and the nucleus is positively charged, why do they not attract and collide with each other? The pull from the nucleus provides a centrifugal force, which is not strong enough to draw the electrons into the nucleus. The pull from the nucleus provides a centripetal force, which is not strong enough to draw the electrons into the nucleus. The pull from the nucleus provides a helical motion. The pull from the nucleus provides a cycloid motion.
