1. The problem statement, all variables and given/known data Use the uncertainty principle to estimate the ground state energy of a particle of mass "m" is moving in a linear potential given by V(x) = ∞ for x≤ 0 V(x) = αx for x ≥ 0 2. Relevant equations ΔxΔp ≥ [STRIKE]h[/STRIKE]/2 3. The attempt at a solution I've looked at a similar problem with the harmonic oscillator potential which was a lot simpler because it is symmetric around x=0 making <x> = 0 and <p> = 0. I know an arbitrary energy level E will cut the potential at x=0 and x = E/α but I am unsure of how to proceed.
