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, burned-out star? The value of the universal gravitational constant is 6.67 × 10^−11N·m2/kg2.
Answer in units of m/s2

  • Physics -

    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
