A proton is confined to a nucleus whose diameter is 5.5*10^-15m. If this distance is considered to be the uncertainty in the position of the proton, what is the minimum uncertainty in its momentum?

I don't really get the uncertainty concept, and how can I do this question?Please help!THANKS A LOT!
