Black holes and gravitons ! Anything wrong here?

If no particle can escape from a black hole, how does quantum mechanics (which postulates gravitons) explain that a black hole’s gravitational field extends beyond its event horizon? If the force of gravity is transmitted by an exchange of gravitons, they’d have to escape from the black hole. I know they’re massless, but so are […]

Solutions to Irodov Problem 1.81 and 1.82

The body mpushes the body Mbackwards. As the bodyM is pushed backwards,m is forced to slide down the incline on M. Let the tension in the string be T and let the normal reaction between the surfaces be N. Further let the acceleration of body M be and let the acceleration of body m with…… Continue reading Solutions to Irodov Problem 1.81 and 1.82
