The nucleus of a 125 Xe atom (an isotope of the element xenon with mass of 125 u) is 6.0 fm in diameter [1 fm = 1 femtometer = 1 x 10-15 m], has 54 protons, and charge q = +54e. (a) What is the electric force on a proton 2.0 fm from the surface of the nucleus? (b) What is the proton's acceleration? HINT: Treat the nucleus as a sphere with a point charge at its center. Remember that a proton has a positive charge of 1.6 x 10-19 C and that the mass of a proton is approximately 1.67 x 10.27 kg. A sketch may also turn out to be useful.
