• (a) Consider an electron whose position is somewhere in an atom of diameter 1 .What is the uncertainty in the electron's momentum? Is this consistent with the binding energy of electrons in atoms? 
• 
  
• (b) Imagine an electron to be somewhere in a nucleus of diameter 10-12 cm. What is the uncertainty in the electron's momentum? Is this consistent with the binding energy of nuclear constituents?
• 
  
• (c) Consider now a neutron, or a proton, to be in such a nucleus. What is the uncertainty in the neutron's, or proton's, momentum? Is this consistent with the binding energy of nuclear constituents
