If you weigh 675 Newton on the earth, find what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 25.0 kilometer? Take the mass of the sun to be ms = 1.99×1030 kilogram, the gravitational constant to be G = 6.67×10-11 Nm2/kg2, and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2.
