The mass of a certain neutron star is
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, burnedout star? The value of the universal gravitational constant is 6.67 × 10^−11N·m2/kg2.
Answer in units of m/s2

g = 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
