Answer:
The potential for r > rb is equal to zero.
Explanation:
For r > rb, the potential is:
![V=\frac{Kq}{r}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7BKq%7D%7Br%7D)
Then, the net potential is:
![V_{(r)} =\frac{K(+\epsilon )}{r} +\frac{K(-\epsilon )}{r}](https://tex.z-dn.net/?f=V_%7B%28r%29%7D%20%3D%5Cfrac%7BK%28%2B%5Cepsilon%20%29%7D%7Br%7D%20%2B%5Cfrac%7BK%28-%5Cepsilon%20%29%7D%7Br%7D)
![K=\frac{1}{4\pi \epsilon _{o} }](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B1%7D%7B4%5Cpi%20%5Cepsilon%20_%7Bo%7D%20%20%7D)
![V_{(r)} =\frac{K(+\epsilon )}{r} -\frac{K(\epsilon )}{r}\\V_{(r)}=0](https://tex.z-dn.net/?f=V_%7B%28r%29%7D%20%3D%5Cfrac%7BK%28%2B%5Cepsilon%20%29%7D%7Br%7D%20-%5Cfrac%7BK%28%5Cepsilon%20%29%7D%7Br%7D%5C%5CV_%7B%28r%29%7D%3D0)
