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 690 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 = 1.99×10³⁰ kg , the gravitational constant to be G = 6.67×10⁻¹¹ N⋅m2/kg2 , and the acceleration due to gravity at the earth’s surface to be g = 9.810 m/s2 .

Express your weight wstar in newtons.
