Question 204207: The Schwarzschild radius describes the critical value to which the radius of a massive body must be reduced fot it to become a black hole.
R= 2GM/c^2
where
G= gravitational constant 6.7x10^-11
M=mass of the object
C= speed of light 3x10^8
The sun has M= 2x10^30 What is Schwarzschild radius for the sun? [Note it's true radius is 700,000.]

The Schwarzschild radius describes the critical value to which the radius of a
massive body must be reduced for it to become a black hole.
R= 2GM/c^2
where
G= gravitational constant 6.7x10^-11
M=mass of the object
C= speed of light 3x10^8
The sun has M= 2x10^30

Wouldn't just be:
R = %282%286.7%2810%5E-11%29%29%2A+2%2810%5E30%29%29%2F%283%2810%5E8%29%29%5E2 = %282%286.7%2810%5E-11%29%29%2A+2%2810%5E30%29%29%2F%289%2810%5E16%29%29 = 26.8%2810%5E%28%2830-11-16%29%29%29%2F9 = 2.98%2810%5E3%29 m
Which is about 3 km
