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

you should already be familiar with the variables involved.
