Particle in a Box: the Ground State Energy of a Particle

question 29

Multiple Choice

Particle in a box: The ground state energy of a particle in a one-dimensional infinite potential well of width 1.5 nm is 20 eV. The ground state energy of the same particle in a one-dimensional finite potential well with U₀ = 0 in the region 0 < x < 1.5 nm, and U₀ = 50 eV everywhere else, would be

• A) less than 20 eV.
• B) greater than 20 eV.
• C) equal to 20 eV.
• D) The particle would not have a ground state.
