Question 163811: 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 = 2 G M / 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 the Schwarzschild radius for the sun? [Note its true radius is 700,000.]

You can put this solution on YOUR website!
R+=+%282+G+M+%29%2F+%28c%5E2%29+
G = gravitational constant 6.7x10%5E-11
M= mass of the object M+=+2x10%5E30
C = speed of light 3x10%5E8+
Four variables. Given 3 of them, find the fourth. So plug in using scientific notation and grind it out
R+=+%282+%2A+6.7x10%5E-11+%2A+2x10%5E30%29%2F%283x10%5E8%29%5E2
R+=+%284+%2A+6.7x10%5E19%29%2F%289x10%5E16%29
R+=+%2826.8x10%5E3%29%2F9
R+=+%282.98x10%5E3%29
