At what location in the space around a black hole does the escape velocity become equal to the speed of light?

Question

Quizplus · Accepted Answer

The escape velocity at the event horizon is equal to the speed of light, which means that any object or radiation that comes closer than the event horizon cannot escape the gravitational pull of the black hole. This is due to the intense curvature of spacetime caused by the massive object, which results in a point of no return called the event horizon. Therefore, choice C is the correct answer as it refers to the location at which the escape velocity equals the speed of light.
