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 Hint: Treat the spherical nucleus as if it were a point charge with the entirety of the +54e charge at the center.
Part A
Another proton (which is not part of the Xenon nucleus) is placed a distance 6.0fm from the surface of the nucleus. What is the magnitude of the electric force on that other proton?
Express your answer using two significant figures.
Part B
What is the proton's acceleration?
