Some believe that the positions of the planets at the time of birth influence the newborn. Others deride this and say that the gravitational force exerted on a baby by the obstetrician is greater than that exerted by the planets. To check this claim, first calculate the gravitational force exerted on a 5.3 kg baby by a 64.0 kg doctor who is 0.7m away.
Calculate the gravitational force exerted on the baby by the planet Jupiter (m=1.9*10^27 kg) at its closest approach to the earth (6.0*10^11 m).
Calculate the gravitational force exerted on the baby by Jupiter at its greatest distance from the earth (9.0*10^11 m).
