   Senario: A string is tied to a ball and swung in a circle at constant velocity.
   
   My question was... which forces are doing work?

   with 500+ posts, you should know that you need to give us your thoughts before we can be of much help.
   
   You should also define the problem better... are you talking about in a gravitational field like on the Earth? Or in space? What is "swinging" the ball?
