Question

Astrology, that unlikely in big pseudo science, makes much of the position of the planets at the moment of birth. The only known force a plan exerts on earth is gravitational. Calculate the gravitational force exerted on a 5.00 kg baby by 130 kg father 0.1 00M away at birth. Calculate the force on the baby due to Jupiter if it is at its closest to the earth, some 6.29×10^11m away, showing it to be comparable to that of the father. The mass of Jupiter is about 1.90×10^27 kilograms. Other objects in the room in the hospital building also exert some more gravitational pull.

Explanation / Answer

Gravitational force is given by (F) = GMm/r2
where r is the distance between the two masses.
Force between baby and father
F = GMm/r2
where m is mass of baby and M is mass of father
r = 0.1 M = 160.934 m
F = 6.67*10-11 *(5*130) /(160.934)2 = 1.67*10-12 N
Now force between baby and jupiter
F = 6.67*10-11 *(5*1.9*1027) /(6.29*1011)2 = 1.6*10-6 N
