The Schwarzchild Radius of a Black Hole Is That Radial

Multiple Choice

The Schwarzchild radius of a black hole is that radial distance from the center of a sphere within which not even light can escape. It was first discovered mathematically by Schwarzchild in 1916 after Einstein published his general relativity theory. It can be calculated from a star's mass M as: R = 2GM/c². If the mass of star G is twice as much as the mass of star H, the average density of star G compared to star H will be

A) twice as much.
B) four times as much.
C) half as much.
D) one-fourth as much.
