The Schwarzschild radius of a black hole depends on
A)the observationally measured radius of the black hole.
B)the way in which the black hole formed.
C)only the mass of the black hole.
D)both the mass and chemical composition of the black hole.

Question

Quizplus · Accepted Answer

The Schwarzschild radius of a black hole depends only on its mass and is given by 2GM/c^2where G is the gravitational constant, M is the mass of the black hole, and c is the speed of light. The chemical composition or the way in which the black hole formed does not affect the Schwarzschild radius.
