Electron and Proton Binding energy

  1. Nov 25, 2012 #1
    1. The problem statement, all variables and given/known data
    neglecting the electric potential energy, calculate the binding energy of the proton and the electron of a hydrogen atom from the following data:

    Radius of electron = 5.29 x 10^-11 m (circular orbital)
    Mass of electron = 9.11 x 10^-31 kg
    Mass of proton = 1.67 x 10^27 kg
    Universal gravitational constant = 6.67 x 10^-11 Nm^2/Kg^2


    3. The attempt at a solution

    So how would i start this problem..
    i know that i would be using the equation Eb = 1/2GMm/Ro
    And i also found that the mass for hydrogen is = 1.67 x 10^-24 g

    It looks like you just have to plug in the values you listed for G, M, m, and Ro. Have you tried doing that?
