Replace the dipole in the program from Section 16.8 with a uniformly charged thin rod. The rod is centered at the origin, and its axis is aligned along the $y$ axis. The rod is $0.05 \mathrm{m}$ long, and its net charge is $-2 \times 10^{-8} \mathrm{C}$. Calcilate the notential difference $V_{B}-V_{A},$ where $A=\langle 0.02,0.02,0\rangle \mathrm{m},$ and $B=\langle 0.12,0.08,0\rangle \mathrm{m}$
Explain how you decided how many point charges to use in modeling the rod.
