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 exert on us is gravitational, so if there is anything to astrology we should expect this force to be significant.

(a) Calculate the gravitational force, in Newtons, exerted on a 4.1kg baby by a 120kg
father who is a distance of 0.18 m away at the time of its birth.
(b) 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, 6.29×10^11m away.
(c) What is the ratio of the force of the father on the baby to the force of Jupiter on the baby?
