5 × 10^30kg (2.5 solar masses) and its radius is 2000 m. What is the acceleration of gravity at the

surface of this condensed, burned-out star? The value of the universal gravitational constant is 6.67 × 10^−11N·m2/kg2.

Answer in units of m/s2

**drwls**, Sunday, December 4, 2011 at 10:53pmg = G M/R^2 is the answer, where

G = 6.67 × 10^−11 N·m^2/kg^2.

R = 2000 m

M = 5 × 10^30 kg
