It is given,electric potential at 5 cm =V1
electric potential at 10 cm =V2
electric potential at 15 cm =V3
We know potential inside a conductor is same everywhere, therefore electric potential at 5 cm and 10 cm distance will be same, that is, V1=V2
Now, electric potential is given as

⇒V3>V1=V2
Thus, electric potential at 5 cm, 10 cm and 15 cm are
V1=V2>V3
