1. The two lowest-energy wave functions of the electron bund to the two protons are symmetric and antisymmetric. Sketch and explain why one has a lower energy while the other has a higher energy.
2. An electron is injected into a space between two large-area metal plates which are in parallel and separated by d. A voltage of + 10V is applied to the right plate relative to the left plate. What is the potential energy curve of the electron? Assume that an electron at rest on the left metal plate is released. Label the total energy and the kinetic energy of the electron throughout the space between the two metal paltes.
