Homework Help: Center of Mass question

  1. Nov 7, 2006 #1
    I really don't understand the concept of center of mass but i have a conceptual question that i am really not sure about.

    Where would you expect the center of mass of a doughnot to be located? Why?

    I mean gut instinct would tell me the center of the doughnut but there is no mass located there so i really need someone to help explain this to me.
