Calculating Energy in Helium Ion Ground State via Bohr Model

[steve233]

Homework Statement

Consider a helium ion with 2 neutrons and 2 protons in the nucleus and 1 bound electron.
Use the Bohr model with corrections for charge and mass of the nucleus.

Calculate the energy in the ground state.

Homework Equations

m*v*r = n*(h/2*pi)

The Attempt at a Solution

Basically I'm confused how to make the corrections to the Bohr model for charge and mass. I'm fine with the rest of the question, I've just never seen an example of making the correction.
Thanks.

The Bohr model of hydrogen atom calculates with the mass of a proton as nucleus mass and 1e charge. What are the mass and charge of the helium nucleus?
