The nucleus of a 125Xe atom (an isotope of the element xenon which has a total of 125 protons and neutrons) is 6.0 fm in diameter. (1fm = 1 femtometer = 1×10−15m) Xenon has 54 protons; therefore, the nucleus has total charge q=+54e. Another proton (which is not part of the Xenon nucleus) is placed a distance d = 6.0 fm from the surface of the nucleus. What is the magnitude of the electric force on that other proton? Hint:...
