By definition we have that gravity is defined as:
 g = G * M / r ^ 2
 Where,
 M = Mass
 r = radius
 G = 6.67 * 10 ^ -11 Nm ^ 2 / kg ^ 2
 Substituting the values we have:
 g = (6.67 * 10 ^ -11) * (1.2 * 10 ^ 31) / (5000) ^ 2
 g = 3.2016E + 13 m / s ^ 2
 Answer:
 the acceleration of gravity at the surface of this condensed, burned-out star is
 g = 3.2016E + 13 m / s ^ 2
