An electron is confined between two perfectly reflecting walls separated by the distance 10 x 10-11m. Use the Heisenberg uncertainty relation δp δx~hbar to estimate the lowest energy that the particle can have (in eV).  (You will need to think about the momentum uncertainty associated with a position uncertainty)
