Homework Statement
What is the velocity of an electron in the hydrogen atom if the centripetal force is supplied by the Coulomb's force between the electron and proton?
Homework Equations
The radius of the electron orbit is 5.29 X 10^-11
The Attempt at a Solution
The answer in the back of the book is 2.19 X 10^6 m/s. I am not really sure how to start this problem since it only gives me the radius. Please help!
