Question

The nucleus of a ^{125}Xe 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 x 10^{-15} m) Xenon has 54 protons; therfore, the nucleus has total charge q = +54e. Another proton (which is not part of the Xenon nucleus) is placed a distance d = 1.0 fm from the surface of the nucleus. (Figure 1) Part A What is the magnitude of the electric force on that other proton? Hint: Treat the spherical nucleus as if it were a point charge with the entirety of the +54e charge at its center. Express your answer using three significant figures. Part B What is the proton's acceleration at its initial distance from the nucleus? Express your answer using three significant figures.
