Two neutral conducting spheres of diameters 8 cm and 2 cm separated with a distance of 15 cm between their centres are joined by a thin conducting wire. A charge of 100 nC is given to one of the spheres and the system is allowed to reach electrostatic equilibrium. The electric potential at a point on the line joining the centres of the two spheres where the net electric field becomes zero is__________________V. (Neglect the charge acquired by the wire and
