Question
Which one of the following is true about black holes?Group of answer choicesNothing can escape from a black holeThey have small size and very large massThey have small mass and large sizeA and BAll of the above
Solution
To determine which statement about black holes is true, let's analyze each option step by step:
-
Nothing can escape from a black hole: This is true. According to general relativity, the gravitational pull of a black hole is so strong that not even light can escape from it once it crosses the event horizon.
-
They have small size and very large mass: This is also true. Black holes are incredibly dense objects with a large amount of mass concentrated in a very small volume, leading to a strong gravitational field.
-
They have small mass and large size: This is false. Black holes are characterized by having a large mass and a relatively small size (in terms of the Schwarzschild radius).
-
A and B: Since both statements A and B are true, this option is correct.
-
All of the above: This is false because statement C is incorrect.
Therefore, the correct answer is:
A and B
