Neutron stars, such as the one at the center of the Crab Nebula, have about the same mass as our sun, but a much smaller diameter.

If you weigh 670 on the earth, what would you weigh on the surface of a neutron star that has the same mass as our sun and a diameter of 20.0 ?

Below is the answer:

W = mg

W = ?
m = 670
g = ?

radius of Neutron star = 11.5 km = 11,500 meters

We need to find g on the Neutron star, so:
g = GM/r^2
g = 6.67 x 10^-11 x 1.99 x 10^30/11,500^2
g = 1 x 10^12

W = 670 x (1 x 10^12)
W = 6.7 x 10^14 N
