Explanation / Answer

Mass on earth = m= W/g = 675/9.81 = 68.8 kg

Mass of Neutron star = M = 1.99*10^30 kg

Radius of Neutron star = 12km = 12000m

Gravitational acceleration on Neutron star = g’ = GM/R^2 = (6.67*10^-11*1.989*10^30)/(12000)^2 = 9.22*10^12 m/s^2

Weight on Neutron start = Wstar = mg’= 68.8*9.22*10^11 = 6.34*10^13 N
