(d) What approximations or simplifying assumptions must you make in these calculations? (Note: Some of these choices are false because they are wrong physics!)
✔Treat Mars as though it were spherically symmetric.
Ignore the effects of the Sun, which alters the gravitational force that one object exerts on another.
✔Treat the humans as though they were points or uniform-density spheres.
O Use the same gravitational constant in (a) and (b) despite its dependence on the size of the masses.
