‘Black hole’ is a
[amp_mcq option1=”huge black star which has zero acceleration due to gravity on its surface” option2=”star which has moderate acceleration due to gravity on its surface” option3=”star which has collapsed into itself and has large acceleration due to gravity on its surface” option4=”star which has collapsed into itself and has zero acceleration due to gravity on its surface” correct=”option3″]

– This collapse compresses the mass into an extremely small volume, resulting in incredibly dense matter.
– The gravitational pull becomes so strong that nothing, not even light, can escape from within a certain boundary called the event horizon.
– The “surface” (event horizon) of a black hole is characterized by an extremely large acceleration due to gravity (often conceptualized by the escape velocity exceeding the speed of light).
– Options A, B, and D are incorrect because a black hole is not a typical star, and it has extremely large, not zero or moderate, acceleration due to gravity at its boundary.
