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. What is the electric force on a proton 1.20 fm from the surface of the nucleus? What is the proton's acceleration?

  1. USE THESE 2 LAWS:

    ELECTRIC FORCE= [COLOUMBS CONTANT* CHARGE1*CHARGE 2] / DISTANCE ^ 2

    AND

    FORCE= MASS (MASS OF PROTON) * ACCELERATION

    --------------

    F = kq1q2 / r²

    = ((8.99 x 10^9 Nm²/C²) x (8.64 x 10^-18 C) x (1.60 x 10^-19 C)) / (1.20 x 10^-15 m)²

    = 8,630 N

    The acceleration is:

    a = F / m

    = 8,630 N / (1.67 x 10^-27 kg)

    = 5.17 x 10^30 m/s²


  2. The force on the proton is:

    F = kq1q2 / r²

    = ((8.99 x 10^9 Nm²/C²) x (8.64 x 10^-18 C) x (1.60 x 10^-19 C)) / (1.20 x 10^-15 m)²

    = 8,630 N

    The acceleration is:

    a = F / m

    = 8,630 N / (1.67 x 10^-27 kg)

    = 5.17 x 10^30 m/s²
