    physics/astronomy

    How could I calculate the acceleration due to gravity right above a star (what would I need to know? Or how do I determine the comparable number to Earth's 9.80 m/s?)?

    (a) at someones feet
    (b) at the top of someones head
    (c) the difference in the magnitude in A and B
    (d) at someones mass of 73.9 kg, calculate the difference in force in newtons and in pounds

    any help would be appreciated!
    Thanks

    magnitude ... \displaystyle g = \frac{GM}{r^2}

    you should already be familiar with the variables involved.
