The nucleus of a 125Xe atom (an isotope of the element xenon with mass 125 u) is 6.0 fm in diameter. It has 54 protons and charge q =+54e.
A) What is the proton's acceleration?
B) What is the electric force on a proton 2.2fm from the surface of the nucleus? Hint: Treat the spherical nucleus as a point charge.
