If you weigh 650 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 18.0 km?
Take the mass of the sun to be = 1.99×10^30 kg, the gravitational constant to be = 6.67×10^(−11) Nm^2/kg^2 , and the acceleration due to gravity at the earth's surface to be = 9.810 m/s^2.
Express your weight in newtons.

Your mass is m = 650N / 9.81m/s^2 = 66.26 kg
r = 18km / 2 = 9000 m
Your weight on the neutron star is
F = G*M*m / r^2 where M = mass of sun (star)
F = 1.09*10^14 N <= ANS
You would need some VERY powerful muscles to even be able to lift a finger!!
But unfortunately your body would be squished flat first...
(and your acceleration due to gravity would be
g = F / m = 1.64 * 10^12 m/s^2`!!)
r = 18km / 2 = 9000 m
