Explanation:
Black Hole Formation:
- A black hole is formed when a massive star collapses under its gravity after running out of fuel for nuclear fusion.
- The core of the star collapses, and the outer layers are expelled in a supernova explosion.
Gravity in Black Holes:
- When a star collapses into a black hole, it becomes extremely dense and compact.
- The gravitational force becomes so strong that even light cannot escape from it, hence the term "black hole."
- The acceleration due to gravity on the surface of a black hole is immense, leading to a singularity at its center.
Accelerating Due to Gravity:
- In the case of a black hole, the acceleration due to gravity is not dependent on the surface but on the mass of the black hole itself.
- The more massive the black hole, the stronger the gravitational pull, resulting in higher acceleration due to gravity.
Correct Answer:
- Option c) "star which has collapsed into itself and has large acceleration due to gravity on its surface" is the correct description of a black hole.
- A black hole is a region in space where the gravitational pull is so intense that nothing, not even light, can escape from it.
