If you weigh 665 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 23.0 km?

Take the mass of the sun to be ms = 1.991030 kg, the gravitational constant to be G = 6.6710-11 N⋅m2/kg2, and the acceleration due to gravity at the earth's surface to be g = 9.810 m/s2.

the answer MasteringPhysics gave me was this. This is over 1011 times your weight on earth! You probably shouldn't venture there ...

F=Gm1m2/r^2 where G is a gravitational constant

F≈m

the greater the mass of planets, the greater the gravitation force experiment by a person

gravity of a planet (a=GM/r^2)

the larger the mass of planet, the larger the gravity of planet

Weight = mass * gravity of the planet

therefore when neutron star has the same mass as our sun, the mass is larger and the gravity of it will be very large
