Today I was assigned a question (that is due tomorrow) and I currenlty have very little idea how to solve it... Any help to get me started here would be greatly appreciated. 1. Use the uncertainty principle to estimate the uncertainty in energy of a proton confined to a nucleus 1.0 x 10^-14m in diameter. Here are the equations we were given 2. (delta x)(delta p) >= h/2pi (delta E)(delta t) >= h/2pi To try and solve it I wasn't really sure where to start because we werent given the uncertainty in time or the uncertainty in momentum so I am not sure how I can make the transition to energy :grumpy: Any help will be greatly appreciated. I do not need someone to solve this for me, please just point me in the right direction so I can learn the material.
