  4. Asked: In:

    If one of the two electrons of a H₂ molecule is removed, we get a hydrogen molecular ion H₂+. In the ground state of an H₂+, the two protons are separated by roughly 1.5 Å, and the electron is roughly 1 Å from each proton. Determine the potential energy of the system. Specify your choice of the zero of potential energy.

  6. Asked: In:

    Figure 2.34 shows a charge array known as an electric quadrupole. For a point on the axis of the quadrupole, obtain the dependence of potential on r for r/a >> 1, and contrast your results with that due to an electric dipole, and an electric monopole (i.e., a single charge).
