Help with Centripetal Acceleration

  1. Feb 7, 2007 #1
    please help:

    The Bohr model of the hydrogen atom has the proton located in the nucleus with the electron orbiting it at a radius of 5.29 x 10^-11m.
    a- What force does the electron experience due to the proton?
    b- what is its centripetal acceleration

    i already figured out part a which is 7.72 x 10^-8, but i have no idea how to find the centripetal acceleration

    Please help

    Do you know how to find the orbital velocity? Mayb you can think of Bohr's quantum condition.

    Can you use Newton's Second Law to find centripetal acceleration? Unless you're in a quantum mechanics class, this problem is as easy as it looks (don't feel bad, a lot of us make the mistake of thinking too hard sometimes).
