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?

  • physics -

    What is wrong with using Newton's Gravitational equation?

    graviatational field g= G Ms*1.60/(10.5E3)^2

  • physics -

    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?

  • physics -

    The "s" is meant to be a subscript to M, representing the mass of the sun.

    It looks like you did it correctly.
