**1. Homework Statement**

A positively charged Helium atom has two protons in the nucleus and one electron in the shell, in a classic model of the atom, this electron is in a circular orbit around the nucleus with an angular momentum of 4.718x10^-34 Js. What is the radius of the orbit?

**2. Homework Equations**

L = sqrt k*e

^{2}*m*r

_{o}

**3. The Attempt at a Solution**

Using that equation, I've tried solving for the radius, but I'm not getting the correct answer. The professor told us it had to do with this equation, so I'm not sure what I'm doing wrong. I've gotten 2.37*10^-10m as my answer.
