Question:
Hello, I am doing a project on schwarzchild radii.
I need someone to help me with this equation R=2GM/c to the 2 power.
the M stands for mass and I think the c stands for speed of light.
also, is does the slash stand for a fraction?.
sorry about all the typos.
please help me.

Replies:
Yes, the slash is a fraction. The quantity G/c^2 can be calculated
since G = 6.673 x 10^-8 cm^/g sec^2
and c = 2.997924562 x 10^10 cm/sec
giving:
G/c^2 = 2.226 x 10^-28 cm/g

So, just multiply the mass by this quantity (and the extra factor
of 2) and you get the radius R. I looked this up in the book:
"Gravitation" by Misner, Thorne and Wheeler, which might be one
place for you to look for further explanations...
