Electron and Proton Binding energy

[Lolagoeslala]

Homework Statement

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

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

i know that i would be using the equation Eb = 1/2GMm/Ro

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