Question

Cara is free falling toward the black hole. What gravitational impact does Cara notice as she passes the event horizon of this black hole? Please explain the answer choice.

1 - high speed.

2 - dilation of the time intervals according to Cara's clock.

3 - contraction of the time intervals according to Cara's clock.

4 - strong gravitational field.

5 - none.

Answer 1

Answer : (4) strong gravitational field.

As we passes the Event horizon, the strength of the gravitational field of the black hole will be stronger.

The event horizon of a black hole is linked to the object's escape velocity — the speed that one would need to exceed to escape the black hole's gravitational pull. The closer someone came to a black hole, the greater the speed they would need to escape that massive gravity. The event horizon is the threshold around the black hole where the escape velocity surpasses the speed of light.

According to Einstein's theory of special relativity, nothing can travel faster through space than the speed of light. This means a black hole's event horizon is essentially the point from which nothing can return.
