Study of schwarzschild radius with reference to the spinning black holes

In this research paper, we have converted the radius of the event horizon of spinning black holes represented by the equation in terms of an another standard parameter known as Chandrashekhar limit(Mch), which is the largest unit of mass, where G = Gravitational constant, M=Mass of the spinning Black hole, c = velocity of light. This work is further extended to derive an expression relating the energy of black holes and the radius of the event horizon of spinning black holes (R's) including a constant term designated by Black hole constant(KBHs) for the spinning black holes (Kerr Black holes) and also calculated the value of Black hole constant for spinning black hole (KBHs).
