Electric potential at a point P due to a charge q is directly proportional to  charge and inversely proportional to the distance between point P and charge.

In the case of charged ring all charges are at equal distance from center .

Half the ring has psitive charge and other half has negative charge .

Hence if we add the electric potential due to all charges in the ring , we get zero.

Electric potential at centre of the ring is zero , if half the ring has positive charge and other half has negative charge.
