"WebAs M=Q, the black hole is extremal, because the two zeros of f (r) have the same value of r, so you get a double root. Although the two horizons are collided in the r coordinates, they are not at the same point! The radius r breaks down, because the distance between the horizons approaches a finite limit at extremality. " - How are black holes studied
