Electron acceleration in its lowest orbit

  1. Feb 15, 2015 #1
    1. The problem statement, all variables and given/known data
    Calculate the centripetal acceleration of an electron in the lowest Bohr orbit.

    2. Relevant equations
    no equations were given but i think i have to use ac = v2/r
    were v = 2.19 x 106 m/s (speed of electron in its lowest orbit)
    r = ao = 5.29 x 10-11m (minimum radius)
    3. The attempt at a solution
    so

    (2.19 x 106m/s)2/(5.29 x 10-11m)

    = 9.07x1022 m/s2

    does this look correct?

    Right if you used the right v and r and the math is right.
    BTW you should also indicate direction since accel. is a vector.

    Yer' welcome! That moniker was given to me at work, my 1st name being rudy. I fear there was some rationale behind it .... :-)
