1) How large is the Schwarzschild Radius for a 100 solar mass black hole? (in km)
Vesc = velocity needed to escape, in m/s
G = a constant, 6.67 x 10-11 N m2/kg2
M = mass of the object you are escaping from, in kg
R = radius of the object you are escaping from, in m
R = 300 Km
2) what formula is correct for the question above
B)
