Charges of $5\times 10^{-6}$ and $-3\times 10^{-6}C$ are kept 16 cm apart. Find the position of points on the line joining the charges where the electric potential is zero.

Two charges $5\times 10^{-8}C$ and $-3\times 10^{-8}C$ are located 16 cm apart. At what point(s) on the line joining the two charges is the electric potential zero? Take the potential at infinity to be zero.
