An electron is held up against the force of gravity by attraction of a fixed proton some distance above it. How far above the electron is the proton?

I donno what to do here? I have nothing to add or i would show my work. Can anyone help me get started.

Thanks
Dx :wink:

Find the point where the gravitational force between the electron and ground is equal to the electrostatic force between the proton and electron.
