What is the energy of the a neutron in a 1-D box when n = 2 and a = 8.50 10-15 m? The mass of a neutron mn = 1.675 10-27 kg. E = n 2 h 2 8 m a 2 Note, you should probably memorize this equation before the final exam. When giving your answer ... Use scientific notation (use the "E" convention) For example, if you wanted to report 1.234 105, you would type 1.234E5 Likewise, if you wanted to report -9.786 10-5, you would type -9.876E-5 Report your answer with 4 significant figures
