Well I setup the relationship in the question where (GM/r^2) = M * (4pi^2r)/T^2, which then simplified to (GM/r^2) = M * (4pi^2r) as T is equal to one. I gave some thought to the idea of density but was unsure on how to implement it as I only got the idea from some other reading.
Homework Statement
Neutron stars are thought to rotate at about 1 revolution every second. What is the minimum mass for the neutron star so that a mass on the star’s surface is in the same situation as a satellite in orbit, that is, the strength of the gravitational field equals the centripetal...
