If you weigh 670 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 21.0 km ?
Take the mass of the sun to be ms = 1.99×1030 kg , the gravitational constant to be G = 6.67×10−11 N⋅m2/kg2 , and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2 .

m = W/g = 68.3 kg
g' = G*M/R² = 3.0098E11 m/s²
W' = m*g' = 2.056E13 N
g' = G*M/R² = 3.0098E11 m/s²
W' = m*g' = 2.056E13 N
