Given, two charge particles
The separation between two charged particle
Now, let's assume the point P between two charged particles where the electric potential is zero is x meter away from
and 
meter away from 
So,
The potential at point P :
Hence the point between two charged particles where the electric potential is zero lies 10cm away from
and 6 cm away from 
Now, Let's assume a point Q which is outside the line segment joining two charges and having zero electric potential .let the point Q lie r meter away from
and (0.16+r) meter away from 
So electric potential at point Q = 0
Hence the Second point where the electric potential is zero is 24cm away from
and 40cm away from
