Using the given charge-to-mass ratios for electrons and protons, and knowing the magnitudes of their charges are equal, what is the ratio of the proton's mass to the electron's? (Note that since the charge-to-mass ratios are given to only three-digit accuracy, your answer may differ from the accepted ratio in the fourth digit.)

In 1911, Ernest Rutherford and his assistants Geiger and Marsden conducted an experiment in which they scattered alpha particles (nuclei of helium atoms) from thin sheets of gold. An alpha particle, having charge +2e and mass 6.64 10-27 kg, is a product of certain radioactive decay's. The results of the experiment led Rutherford to the idea that most of an atoms mass is in a very small nucleus, with electrons in orbit around it. (This is the planetary model of the atom, which well study in Chapter 42.) Assume an alpha particle, initially very far from a stationary gold nucleus, is fired with a velocity of 2.00 107 m/s directly toward the nucleus (charge +79e). What is the smallest distance between the alpha particle and the nucleus before the alpha particle reverses direction? Assume the gold nucleus remains stationary.

In the famous “oil drop experiment,” Robert Millikan exposed oil drops to X-rays to remove electrons from them and then suspended them in mid-air using an electric field. The experiment determined the “fundamental charge” of the electron. Answer the following questions about the experiment without copying things from the text or from the internet.In other words, demonstrate an understanding of the scientific principles behind the experiment: a. Why did an electric field make the oil drops float in mid-air? b. How did the strength of the electric field and the masses of the oil drops lead Millikan to the value of the “fundamental charge” of the electron?
