A charge Q = -520 nC is uniformly distributed on a ring of 2.4 m radius. A charges q = +370 nC is placed at the centre of the ring. Points A and B are located on the axis of the ring, as shown in figure, the electric potential is equal to zero at a point on the axis of the ring. The distance of this point from the centre of the ring is closest to
