Question

How close, r, to the center of a neutron star would a manned satellite be orbiting if it were at the location where the gravitational force from the star equaled the gravitational force of the Earth's surface?


RN = neutron star radius = 1 × 104 km
M N = neutron star mass = 3 × 1030 kg
G = universal gravitational constant = 6.67 × 10-11 N m2 / kg2
g = Earth gravitational acceleration = 9.807 m/s²
