let three charges are placed at the vertices of equilateral triangle then net potential at any point is given by


V = V1 +V2 + V3


V = kq/r , so


V1,V2,V3 = Kq/r1 , kq/r2 , kq/r3


V = kq(1/r1+1/r2+1/r3)


since charges are same & of same sign so kq is taken out of brakett now


V is 0 if q is 0 or if r1,r2,r3 all are infinity


so , the only condition is that a point shoud be at infinity ...


inside the triangle only electric field can be 0 not potential...
