Problem $5$: $(13\%$ of Assignment Value$)$

Dipoles play a critical role in the electric responses of ionic fluids. In the figure at the right is shown a molecular dipole approximated by two point charges separated by a rigid bar. Some equipotential lines are drawn showing what the potential is at various points $($using an arbitrary scale$).$ On the figure are drawn two lines labeled I and II$.$

Part $($a$)$

Which graph of the electrostatic potential would a $C{l}^{-}$ion measure as it moved along line I?

Part $($b$)$

Which graph of the electrostatic potential would a $C{l}^{-}$ion measure as it moved along line II$?$

Part $($c$)$

How would your answers change if the electrostatic potential were being probed by a $N{a}^{+}$ion instead of by a $C{l}^{-}$ion?
