Astrology, that unlikely and vague pseudoscience,makes much of the position of the planets at the moment of birth. The only known force a planet exerts on earth is gravitational. (A) Calculate the gravitational force exerted on a 3.00 kg baby by a 130kg father 0.150 m away at birth (assisting so he is close). Answer in N (B) Calculate the five on the baby due to Jupiter if it's at its closest to the earth, some 6.29x 10^11 m away, showing it to be comparable to that of the father. The mass of Jupiter is about 1.90 x10^27 kg. Other objects in the room and the hospital building also exert similar gravitational force. (Of course, there could be an unknown force acting, but scientist first need to be convinced that there is even an effect, much less that an unknown force causes it.) Answer in N
