Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of one’s birth. the only known force that a planet could exerts on us is gravitational, so if there is anything to astrology we should expect this force to be significant.
Calculate the gravitational force, in newtons, exerted on a 4.1 kg baby by a 75 kg father who is a distance of 0.16 m away at the time of its birth.
Calculate the force on the baby, in newtons, due to Jupiter (the largest planet, which has a mass of 1.90 × 10^27 kg) if it is at its closest distance to Earth, 6.29 × 10^11 m away.
What is the ratio of the force of the father on the baby to the force of Jupiter on the baby?
