Calculate the force of gravity between a newborn baby of mass 4 kg and the obstetrician of mass 75 kg, who is 0.5 m from the baby.
N
Which exerts more gravitational force on the baby, Mars or the obstetrician, given that Mars has a mass of 6.4 1023 kg and is 8. 1010 m from Earth?
obstetrician
Mars
both exert the same force
By how much?
hint: Part C is asking for the ratio between the forces in Part A and Part B. Divide the bigger force by the smaller force to get your answer (should be greater than 1).
