**1. The particle in a box model is often used to make rough estimates of ground state energies. Suppose that you have a neutron confined to a one-dimensional box of length equal say 1x10**

^{-14}m. What is the ground state energy of the confined neutron? **the answer it wants is in MeV*****2. equation for the minimum possible energy (ground state; n=1).... E=(h**

^{2})/(8mL^{2})>h=6.63e

^{-34}Js

>I use 1x10

^{-14}m as L (is that right)

**3. i should be able to just plug in the values and get the answer, but it does not work. after plugging my values in (using 1x10**

^{-14}m as L) i get 3.29e^{-13}, which doesn't work. then i tried converting it to MeV by dividing by 1.6e^{-19}(convert J to eV) then dividing again by 10^{6 }(converts to Mega) which gives me 2.1, but that doesn't work either... what am i missing?
