How is the escape speed related to the mass of a black hole?.
- A.Escape speed decreases with increasing mass
- B.Escape speed increases with increasing mass
- C.Escape speed is independent of mass
- D.Escape speed is constant for all black holes
Model answer
What a good answer should say
- Escape speed increases with increasing mass
Explanation
Why this works
The escape speed from a black hole increases with mass, as a more massive black hole exerts a stronger gravitational pull, requiring a higher speed to escape.
