In a certain region of space, a particle is described by the wave function ?(x) = Cxe^(-bx) where c and b are real constants.
By substituting into the Schorodinger equation, find the potential energy in this region and also find the energy of the particle.
(Hint: Your solution must give an energy that is a constant everywhere in the region, independet of x)
