Question
Transcribed Image Text:(a) Calculate the magnitude of the gravitational force exerted by Mars on a 65 kg human standing on the surface of Mars. (The mass of Mars is 6.4x1023 kg and its
radius is 3.4x106 m.)

(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.
