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? (The charge-to-mass ratios for electrons and protons are −1.7588×1011 C/kg and 9.5788e7 C/kg , respectively. Note that since the charge-to-mass ratios are given to five-digit accuracy, your answer may differ from the accepted ratio. Round your answer to at least five significant figures.)
Mp/Me =
Calculate the density of proton. The estimated diameter of the proton will be generated by the computer from a range of possible values. (The text's is probably wrong.) Calculate the (volume) density of the proton in kg/mm3. You may be able to use exponential notation: 4.56e7.
m = 1.67*10-27 kg
diameter = 1.6*10-15 m = 1.6 fm
Calculate the theoretical value of e/m using the known values of the electric charge and electron mass (both of which you can look up in a textbook).

- All stars have to be electrically charge neutral, since the gravitational force is about 1036 times weaker than the electromagnetic force. Calculate what is the maximum ratio of charged particle per nucleon Z/A you can have in a star, so it does not expel a proton from the surface. In other words, the gravitational force between a proton and the remaining star must be larger than the Coulomb's force.
