    1. The problem statement, all variables and given/known data
    what is the gravitational field strength on the surface of a star that has a radius of 5.0 x 10^6km and a mass of 6.0 x 10^33 kg


    2. Relevant equations

    i tried the F=G MM/r^2

    How do the mass and radius compare to the earth - I expect mass is much bigger. That could give you the answer by comparison.
