1. Suppose that the potential seen by a neutron in a nucleus can be represented by a square well of width 10^(-12)cm with very high walls. What is minimum KE of the neutron in this potential ?

2. K.E = (1/2)mv^2

3. Its an isolated system, so it drops into its lowest energy state and the energy of the lowest state is higher than the minimum of potential energy. How to calculate the minimum potential energy with the width of well ? What to do with the width of well ?

I think you are supposed to estimate it using the Heisenberg uncertainty relation.
