From (12), it is clear that the surface gravity of black hole is inversely proportional to its mass and the different black holes will have different surface gravity. The present research paper derives a formula for gravitational force acting between the black hole and light particle passing near the radius of event horizon of black holes and calculates also their values of different test black holes existing in only X-ray binaries (XRBs). here the parameter r denotes two possible horizon called outer and inner horizons for sign (+) and (−) respectively [3,8,9]. Einstein equations are simply the requirement that the metric is Ricci flat, R µ⌫ =0 (4.5) These deceptively simple equations hold a myriad of surprises. Gravitational force between spinning black holes & light particles in AGN. In this paper, I examine They conclude that only an upper limit of, can be put on the central mass. From Figures 1 and 2, it is clear that the gravitational force acting between the black holes and light particle decreases gradually with increase of the radius of the event horizon of different test nonspinning and spinning black holes for a given wavelength of radiation. As a result, black holes are not visible to the eye, although they can be detected from the behavior of light and matter nearby. The equation for the escape velocity of a Black hole is obtained by substituting the speed of light in the standard escape velocity equation. That is, The light particle (light wave) of shorter wavelength has attracted more than that of longer wavelength for constant surface gravity. M. Kanarev, Journal of Theoretics, Vol. Formula for the Gravitational Force Acting between the Black Hole and Light Particle. In course of the present research work, we have concluded that most of the characteristics of non-spinning or spinning black holes in Active Galactic Nuclei (AGN) are the same to that of cases of X-ray binaries (XRBs), but differing in some sense. The above relation shows that the force of attraction acting between black hole and light particle is inversely proportional to the wavelength of electromagnetic wave coming towards the event horizon of black holes. The Equntions (1) and (2) represent the gravitational force acting on light particle due to non-spinning and spinning black holes. J.

For light rays $\mbox{d}s$ is always zero, and we can use this to calculate the velocity of the light ray. The present work is also concerned with the force acting upon a body deviated from its geodesic path due to its being at rest in a gravitational field. The event horizon is not a physical boundary but the point-of-no-return for anything that crosses it. In 1997, Lerner discussed the problem of the deflection of light in a medium with varying refractive index applied to the motion of light in a weak Schwarzschild gravitational field [3]. L.
