What is the magnitude of the gravitational field at the surface of a neutron star whose mass is 1.60 times the mass of the Sun and whose radius is 10.5 km?

What is wrong with using Newton's Gravitational equation?
graviatational field g= G Ms*1.60/(10.5E3)^2

mass of the sun is 1.99E30 kg.
so the mass of the neutron star is 3.184E30 kg.
i solved for g using g=GM/R^2
what is s?
i solved for g using my equation and got 1.93E18 m/s^2. is that right?

The "s" is meant to be a subscript to M, representing the mass of the sun.
It looks like you did it correctly.
