Homework Help: Kinetic Energy of Ion accelerated across potential difference

  1. Sep 11, 2009 #1
    An ion of 64Zn30+ with an initial kinetic energy of 9.88 keV is accelerated across a potential difference of 277 Volts. What is its kinetic energy after acceleration (in keV)?

    Welcome to PF!

    Hi iuchem16! Welcome to PF! :smile:
    What is the definition of potential difference, and its relation to potential energy ? :wink:

    Show us what you've tried. :smile:

    A potential difference of 277 volts will transfer energy of 277 ev per unit charge to the ion.

    Take the charge of your ion, multiply by 277 ev, add to 9.88...
